The correct answer is B. played.
The sentence “He used to play cricket” is in the past simple tense. The past simple tense is used to talk about things that happened in the past and are not happening now. In this case, the speaker is talking about something that the man used to do, but does not do anymore.
The other options are incorrect because they are not in the past simple tense. Option A, “play”, is in the present tense. Option C, “playing”, is in the present participle tense. Option D, “plays”, is in the simple present tense.
Here are some examples of how the past simple tense can be used:
- I went to the store yesterday.
- She ate dinner at 6pm.
- We played football last weekend.
- They watched TV last night.
