What have you tried so far in View and Controller? You have to post your view and controller and by the way you don't have to submit the correct option ID from view. It has to come from server to compare the selected Option

Hi Rahul Yadav,
Seems your question needs more details.
1. Are you loading data from any DB?
2. How you are giving a control to the user to select the answer?

If it is a Radio Button list While on click of Post button you can add a click event in JavaScript and you can read the selected option. From JavaScript function you can call controller and pass the data.

In that method you can get the answer by passing QuestionNo to DB.

Here my Example with a Check Box list (as i also don't have much idea about MVC):

$("#PostAnswer").click(function () {  //<pre>PostAnswer is Button ID

        var questionlist = [], counter = 0;
        
        $('.chkbox1').each(function () {
            if ($(this).is(':checked')) {
               var questionID = evalVM[0].ID;
                var id = $(this).attr('ID');
                var question= {
                    QuestionID: questionID,
                    answerID  : id 
                };
                questionlist .push(question);
            }
        });</pre>

 Then you can call the controller by passing the list

var url = baseurl + 'EvaluationController/ValidateAnswers
 $.ajax({
        url: url,
        type: 'POST',
        dataType: 'json',
        data: JSON.stringify(questionlist ),
        contentType: 'application/json; charset=utf-8',
        success: function (result) {
            if (result > 0) {
                alert('');
            }
        }
    });

[HttpPost]
        public JsonResult ValidateAnswers(List<evalmodel> evalVM= null)

From controller you can validate against DB.

Sorry If anything is wrong. Even am also new to MVC, But i explained how we are using in our current project.</evalmodel>
