Question

Fill in the blank with the most appropriate word.
He has an exam tomorrow, so he ____ study.

• A. ought
• B. must
• C. had to
• D. must have

Answer 1

The correct option is B must

The sentence indicates that the subject has an exam tomorrow and thus, it can be concluded that the subject needs to study. Thus, the answer must mean 'needs to'.

Option A is incorrect. 'ought' means 'obligated' and not 'needs to'. Thus, it does not have the required meaning.

Option B is correct. 'must' means 'needs to'. Thus, it has the correct meaning and is the correct answer.

Option C is incorrect. 'had to' means 'was required to' and not 'needs to'. Thus, it does not have the required meaning.

Option D is incorrect. 'must have' indicates an opinion about the past and does not mean 'needs to'. Thus, it does not have the required meaning.
