Answer 1

private System.Random rnd = new System.Random();

    void Start()
    {
         List<string> ranS = new List<string>()
         {
             "a",
             "b",
             "c"
         };

         Debug.Log(ranS[rnd.Next(0, 3)]);
    }

But always in rnd.Next(0, 3) you need to put 1 more than there is, and we start not from 1 but from 0
