Question

Fill in the blank with the appropriate verb.
According to the school rules, every student _______ attend the morning assembly.

• A. Might
• B. Must
• C. Can
• D. Would

Answer 1

The correct option is B Must

Here, 'must' in simple present tense is correct because it is used to say that something is necessary or very important (sometimes involving a rule or a law). Here, it is a rule for every student to attend the morning assembly.
'Might' is incorrect because it is used to make a polite suggestion or to ask permission politely.
'Can' is incorrect because it is used to say that it is possible for somebody/something to do something or for something to happen.
'Would' as a modal verb is incorrect because it is used for talking about the result of an event that you imagine.
