How to remove a piece in a string-CodePudding

So I am making a quest system, and I want to randomly choose a quest, but i dont want it to choose the same one again. Here is the piece on code for the string. I cant find any good answer. This is a more simple line of code.

string[] QuestChoose = new string[] {"Quest1", "Quest2", "Quest3"};

convert to List and Operate this list

3 methods come to mind:

Convert to a List and call Remove().
Write null into the array after having read the quest and when selecting a quest, always search for the next suggestion if null was selected.
Keep a separate data structure like a HashSet<int> where you add the index in the array whenever a quest has been used. Then check for Contains on your ID when selecting.
