Should I use which or what?
If I am referring to the alternatives of a quiz (with a limited number of options) and I want to ask someone the correct alternative, should I say:
What is the correct alternative?
Or
Which is the correct alternative?
Solution 1:
"Which" is preferred in the scenario of a limited number of options. So in your case, as you are presenting a quiz, where participants would pick one between multiple options,
Which (one) is the correct alternative/ answer/ option?
would be the most appropriate.
