Problem disabling specific select dropdown fields using Javascript

Question

Am working on an application whereby I have some cards that have select dropdown fields. On the Cards I have written a JavaScript logic whereby if the user selected a wife or husband as an option on the any of the cards select drop down, any of the other husband or wife dropdown field should disable.

The problem is the other cards do not disable when I select an option from any card. Basically I want when the user selects wife or husband option on any card, all other husband or wife options on other cards should disable instantly.

I get this error in console:

TypeError: document.querySelectorAll(...).addEventListener is not a function

Javascript code

document.querySelectorAll('.otherMenu').addEventListener('change', function() {
    var selectedOption = this.value;
    var selectWife = document.querySelectorAll('.otherMenu option[value="Wife"]');
    var selectHusband = document.querySelectorAll('.otherMenu option[value="Husband"]');
        selectWife.forEach(function(option) {
            option.disabled = selectedOption === 'Wife';
        });
        selectHusband.forEach(function(option) {
            option.disabled = selectedOption === 'Husband';
        });
});

I think you cant add an eventlistener on a list of menus it must be done for each menu

var menus = document.querySelectorAll('.otherMenu');
for (let menu of menus) {
    menu.addEventListener('change', function () {
        var selectedOption = this.value;
        var selectWife = document.querySelectorAll('.otherMenu option[value="Wife"]');
        var selectHusband = document.querySelectorAll('.otherMenu option[value="Husband"]');
        selectWife.forEach(function (option) {
            option.disabled = selectedOption === 'Wife';
        });
        selectHusband.forEach(function (option) {
            option.disabled = selectedOption === 'Husband';
        });
    });
}

Firstly you shouldnt use the same ids for inputs in every card. If my answer solved your problem can you please mark it as correct.
