3.There’s a man lying down on the pavement over there. Do you think he hurt himself? (use a suitable modal verb)

There’s a man lying down on the pavement over there. Do you think he may/might have hurt himself?

Explanation:

In the second sentence, modal verbs may and might can be used. These verbs are used to express the possibility of something happening.

The constructions may/might + have + past participle and may/might + be + present participle are used to talk about possible events in the past, present, and future. Since the given event took place in the past (the man is now lying on the pavement because he may have hurt himself earlier), the construction with the past participle will be used. That's how we'll get the sentence:

Do you think he may/might have hurt himself?

i'm pretty sure i had this question the other day and b was the right answer.
