Which sentence uses the exact phrase 'Mary had better go to work today' to convey advice?

• A. Mary had better go to work today.
• B. Mary should go to work today.
• C. Mary must go to work today.
• D. Mary will go to work today.

Answer: (A)

This tests recognizing how to convey advice with the exact phrasing. The sentence uses the fixed construction had better to express strong advice with an implied consequence if she doesn’t act. That precise wording is what the prompt asks for. Other options rely on different modals—should offers a suggestion, not the same force or exact wording; must states obligation with stronger force but isn’t the exact phrase; will describes future action rather than giving advice in this specific form. So the sentence with the exact phrase is the one that conveys advice in the requested way.
