Question:

Which of the following is an example of a correctly punctuated sentence?

A “What would you prefer to do on vacation—visit a museum or go on a walking tour?” asked my father .

In this sentence, the question mark should go at the end of the sentence (“…walking tour?”). There is no need to have a comma following the question mark. In this context, either the colon or the dash would be acceptable.
