Answer 1

Your method in your controller is decorated with HttpPost, while in your ajax you have specified the type of your request is get . You can either change your method to get like this:

[HttpGet]
public JsonResult GetSelectedQuestion(int prefix)
{
}

Or change your request type to post in your Ajax call:

$.ajax({
    url: "@Url.Action("GetSelectedQuestion", "ConductSurveyController")",
    data: { prefix: $('#DDlSurvey').val() },
    type: "Post",

Also the Controller is redundant in ConductSurveyController, you need to remove it and simply call it as ConductSurvey:

url: '@Url.Action("GetSelectedQuestion", "ConductSurvey")',
