Answer 3

Prepare a string array containing all the valid option, then use `Contains` method of the array to check whether the given input (<selection>) is one of the elements in the array.

string[] choices = { "rock", "paper", "scissor" };
if(choices.Contains("paper"))
{
// ok
}
else
{
// not a valid option
}

Is switch statement allowed? if it is, then you can try switching the valid options instead ...
