Answer 1

Hint: Verbs are words that describe an action, an occurrence, or a state of being. It's a term that expresses an action, an event, or a state of being through syntax. The infinitive is the most fundamental form in English, and it can be used with or without the particle to. Verbs are inflected in several languages to indicate tense, aspect, mood, and voice.

Complete answer:
In the above sentence, we have to use such a verb that will show the least possibility of something because we have to indicate that Margaret does not know what to do.

Let us look at the given options:
A) can't: This option is incorrect because the word ‘can't’ is used to express that something is now unattainable whereas in the above sentence we have to show that there is no possibility that Margaret will know what to do.
B) couldn't: This option is incorrect because in the past, the word ‘couldn't’ was used to express incapacity. But the above sentence is in the present tense and requires the use of the future tense of the verb because the other person has not yet asked Margaret.
C) mustn't: This option is incorrect because the word mustn't is used to express prohibition whereas the speaker is just making an assumption that Margaret will not know what to do.
D) won't: In the above sentence, Margaret has the smallest probability of giving advice. As a result, the right answer is D: won't.

Thus, the correct answer is Option D) Won’t.

Note: Intransitive, transitive, linking, and passive verbs are the four types of verbs. Passive verbs are in the passive voice, whereas intransitive and transitive verbs are in the active voice. Verbs that convey activity but do not accept an object are known as intransitive verbs.
