Question that needs a selection

Question

What do you call a question that needs a selection? For example:

Is an argument true until proven false or vice-versa?

Answer 1

I'd call that an "either-or" question, or if there are more than two choices, a "multiple-choice" question.

Answer 2

A question that invites the reader to choose one of two propositions, especially where those propositions are mutually exclusive, might be called a dichotomous question.

A dichotomous question might require a yes or no response, which would make it a closed-ended question but a defining attribute of a dichotomy is that it poses two choices, or "selections" to use your word.
