• "Ought to" expresses a moral duty or strong advice, making it the best choice here.

• "May" expresses possibility or permission, which does not fit the context.

• "Had to" refers to a past obligation, but the sentence is in the present.

• "Will" expresses future certainty but does not indicate obligation.
