The correct answer to the question "Use (used to): He / play golf every weekend" is "Did he use to play golf every weekend?"
When using "used to" to talk about past habits or actions that happened regularly in the past but no longer happen in the present, we need to use the auxiliary verb "did" to form questions in the past simple tense. So, the correct formation of this question is with "Did he use to" at the beginning.
