I have a radio button named "Choose" with the options yes and no. If I select any one of the options and click the button labeled "clear", I need to clear the selected option, using javascript. How can I accomplish that?

You don't need to have unique id for the elements, you can access them by their name attribute:

If you're using name="Choose", then:

With recent jQuery

$('input[name=Choose]').prop('checked',false);

With old jQuery (<1.6)

$('input[name=Choose]').attr('checked',false);

or in pure JavaScript

var ele = document.getElementsByName("Choose");
for(var i=0;i<ele.length;i++)
    ele[i].checked = false;

If you do not intend to use jQuery, you can use simple javascript like this

document.querySelector('input[name="Choose"]:checked').checked = false;

Only benefit with this is you don't have to use loops for two radio buttons

This should work. Make sure each button has a unique ID. (Replace Choose_Yes and Choose_No with the IDs of your two radio buttons)

document.getElementById("Choose_Yes").checked = false;
document.getElementById("Choose_No").checked = false;

An example of how the radio buttons should be named:

<input type="radio" name="Choose" id="Choose_Yes" value="1" /> Yes
<input type="radio" name="Choose" id="Choose_No" value="2" /> No

If i have one common id means, then how could i proceed?
You need to change it to separate IDs. You should not have more than one of the same ID on a page. You need to use the same Name to make it a radio button group, but the ID has to be unique.
@i2ijeya I would use a library such as jquery.com where I could select by class if I wanted to select more radio buttons at once. You could also use document.getElementsByName("Choose").
While jQuery is great, it does not need to be used for every little bit of JavaScript. In this case it would just be unnecessary overhead for something that's pretty simple to do in plain JavaScript.
As David says, you can access by name, so id isn't required for this function. Also, I suspect a typo -- your value is the same for both buttons.

An ES6 approach to clearing a group of radio buttons:

    Array.from( document.querySelectorAll('input[name="group-name"]:checked'), input => input.checked = false );

Wouldn't a better alternative be to just add a third button ("neither") that will give the same result as none selected?

I quote this solution. Radio buttons, as a UI element, are not meant to be reset (ie: none of them checked). They are designed to start with 1 option checked, and the possibility to change it. You may consider to change your radio buttons to a dropdown list: {empty}|Yes|No
@Filini Windows forms programming has 3-state radio buttons, not sure why they can't be used for the Web.
@Shawn, are you sure you are not thinking about tri-state checkboxes? Anyway, how does this relate to the possibility to reset a radio button?
@Filini - sometimes you might need to reset the radio buttons, all unchecked. I faced situation in a Quiz App - when user restarts the quiz, all the options (radio buttons) should be unchecked (created in AngularJS).

In my case this got the job done:

const chbx = document.getElementsByName("input_name");

for(let i=0; i < chbx.length; i++) {
    chbx[i].checked = false;
}

Simple, no jQuery required:

<a href="javascript:clearChecks('group1')">clear</a>

<script type="text/javascript">
function clearChecks(radioName) {
    var radio = document.form1[radioName]
    for(x=0;x<radio.length;x++) {
        document.form1[radioName][x].checked = false
    }
}

</script>

YES<input type="radio" name="group1" id="sal" value="YES" >

NO<input type="radio" name="group1" id="sal1" value="NO" >

<input type="button" onclick="document.getElementById('sal').checked=false;document.getElementById('sal1').checked=false">

That won't actually work if NO is checked because javascript will never see the 2nd element with the same ID.
-1. It's invalid HTML to have multiple elements with the same ID.

if the id of the radio buttons are 'male' and 'female', value reset can be done by using jquery

$('input[id=male]').attr('checked',false);
$('input[id=female]').attr('checked',false);

<form>
  <input type="radio" name="btn"> Item1
  <input type="radio" name="btn"> Item2<br>
  <input type="reset">
</form>

This could work..
