Answer is Right!
Answer is Wrong!
The correct answer is A. have broken.
The sentence is in the present tense, so the verb “break” should be in the
present perfect tense. The present perfect tense is used to talk about things that have happened in the past but have a connection to the present. In this case, the speaker is talking about an event that happened in the past (breaking their leg) that has a connection to the present (being unable to go on the excursion).The other options are incorrect because they are not in the present perfect tense. Option B, break, is in the simple present tense. This tense is used to talk about things that happen regularly or repeatedly. Option C, had broken, is in the past perfect tense. This tense is used to talk about things that happened before another event in the past. Option D, No improvement, is incorrect because the sentence is already correct.
