How to add IList<> in ASP.NET MVC model?

I am trying to create a question and answers page. In which I am adding a question through textbox and want to add 4 textboxes to get answer option. I am using this model.

public class Question
    {
        public virtual int ID { get; set; }
        public virtual QPad QPad { get; set; }
        [Display(Name = "Add Question")]
        public virtual string QuestionText { get; set; }        
        [Display(Name = "Add Options")]
        public virtual IList<string> AnswerOption { get; set; }
    }

But now in a create action's view of QuestionController

My controller is:

[HttpPost]
        public ActionResult Index(int qId, Question ques )
        {
            if (ModelState.IsValid)
            {
                var QPads = _db.QPads.Single(r => r.ID == qId);
                QPads.Questions.Add(ques);
                _db.SaveChanges();
                return RedirectToAction("Index", "QPad");
            }
            else
            {
                return View(ques);
            }
        }

I want to add editor for question text and options, I use

<div class="editor-label">
            @Html.LabelFor(model => model.QuestionText)
        </div>
        <div class="editor-field">
            @Html.EditorFor(model => model.QuestionText)
            @Html.ValidationMessageFor(model => model.QuestionText)
        </div>
/// ?????What for  4 Options boxes///////?

I am not able to add option boxes. Am I using correct approach in models or should I change something ?

or can I customize that user itself select how much options he wants to add ?

Please suggest ?

You might think about adding an AnswerOption Entity to your data model, so you can define, how many options each question has.

Then you could do something like 

foreach(var option in model.options){
 @Html.EditorFor(option);
 @Html.ValidationMessageFor(option);
}

When you say "option boxes" I assume you mean radio buttons. If so then you can use the RadioButton Html helper, something like this.

<div class="editor-field">
    @foreach(var myValue in Model.AnswerOptions) {
        @Html.RadioButton("NAME_OF_LIST_FOR_ANSWERS", myValue)
    }
</div>

If the use is always allowed to add four options then I may try something like this.

<div class="editor-label">
  @Html.LabelFor(model => model.QuestionText)
</div>
<div class="editor-field">
  @Html.EditorFor(model => model.QuestionText)
   @Html.ValidationMessageFor(model => model.QuestionText)
</div>
@for(int i = 0; i < 4; i++)
{
  <div class="editor-field">
     @Html.EditorFor(model => model.AnswerOption[i])
     @Html.ValidationMessageFor(model => model.AnswerOption[i])
  </div>
}
