How to have a list or an array of string in my model of ASP.NET MVC_CodeFirst

Question

I want to use Code-first Database.This is my Model of asp MVC

Model:

public class Question
{
    public virtual int Id { get; set; }
    public virtual string Qu { get; set; }
    public virtual string Ans { get; set; }
    public virtual List<string> KeyWords { get; set; }
}

Each object of Question must have a list of KeyWords. Is it a correct way or it will be better if I have a model of KeyWords then here create a list of object keyword?

Appreciate your help, thanks!

I would think if you want to store the data in a database you would need to normalize the code. I would do it this way:

public class Question
{
    public int Id { get; set; }
    public string Qu { get; set; }
    public string Ans { get; set; }
    public virtual List<string> KeyWords { get; set; }
 }
public class Keyword
 {
    public int Id {get;set;}
    [ForeignKey("question")]
    public int QuestionID {get;set;}
    public string keyword {get;set;}
    public virtual Question question {get;set;}
 }
public QuestionModel :DBContext
 {
    public virtual DBSet<Question> Questions {get;set;}
    public virtual DBSEt<Keywords> Keyword {get;set:}
 }

I use ICollection<> instead of List for the virtual collections but I'm not sure it matters.
