Add data to table referenced with foreign key in Rails

I have two models: Question and Options. Question has has_many relation with Options. I need to add options to question whenever I create a new question. I have written the code but I am not able to send data to the options of Question model. Whenever I create the question and add options in the form, the options to that question are empty. Where is the mistake?

Models

class Question < ApplicationRecord
  belongs_to :user
  has_many :options

  accepts_nested_attributes_for :options
end

class Option < ApplicationRecord
  belongs_to :question
end

questions_controller.rb

# GET /questions/new
  def new
    @question = Question.new
    @question.options.build(params[:options])
  end

  # GET /questions/1/edit
  def edit
  end

  # POST /questions
  # POST /questions.json
  def create
    @question = Question.new(question_params)
    puts("---------------------Question options: --------------------------------------------")
    puts(@question.options)    
    @question.user = current_user

    respond_to do |format|
      if @question.save
        format.html { redirect_to @question, notice: 'Question was successfully created.' }
        format.json { render :show, status: :created, location: @question }
      else
        format.html { render :new }
        format.json { render json: @question.errors, status: :unprocessable_entity }
      end
    end
  end

  # PATCH/PUT /questions/1
  # PATCH/PUT /questions/1.json
  def update
    respond_to do |format|
      if @question.update(question_params)
        format.html { redirect_to @question, notice: 'Question was successfully updated.' }
        format.json { render :show, status: :ok, location: @question }
      else
        format.html { render :edit }
        format.json { render json: @question.errors, status: :unprocessable_entity }
      end
    end

_form.html.erb

<%= form_with(model: question, local: true) do |form| %>
  <% if question.errors.any? %>
    <div id="error_explanation">
      <h2><%= pluralize(question.errors.count, "error") %> prohibited this question from being saved:</h2>
