Question

Fill in the blank with an appropriate modal that denotes certainty:

You _____ come and have dinner with me.

• A. must
• B. dare
• C. need
• D. ought

Answer 1

The correct option is A must

Option A is the correct answer because 'must' expresses compulsion or strong obligation. It is much stronger than 'should', it can also express probability or likelihood, as in this case.

Option C and D are wrong because 'need' and 'ought' are used to express duty, necessity, or moral obligation which is not correct here. They are followed by 'to'.

Option B is incorrect because 'dare' means to ask someone to do something that involves risk, which is not correct here.
