The correct answer is C. He was saved by me from the clutches of pickpockets.
The other options are incorrect because they do not accurately reflect the tense of the sentence. Option A, He may have been saved by me from the clutches of pickpockets, uses the past modal verb “may”. This verb is used to express possibility or uncertainty. In this case, it would suggest that there is a chance that the person was saved, but it is not certain. Option B, He could be saved by me from the clutches of pickpockets, uses the past modal verb “could”. This verb is used to express ability or permission. In this case, it would suggest that the person was able to be saved, but it is not certain that they were actually saved. Option D, He has been saved by me from the clutches of pickpockets, uses the present perfect tense. This tense is used to express actions that have happened in the past but have an effect on the present. In this case, it would suggest that the person was saved at some point in the past, but it is not clear when.
The sentence “I saved him from the clutches of pickpockets” is in the past tense. This means that the action of saving the person happened at a specific point in the past. The other options do not accurately reflect this tense.
