Correct option is B
Explanation:
· The structure "while he ___" refers to an ongoing past action, requiring past continuous tense.
· "Was celebrating" is correct.
· The simple past "celebrated" doesn't capture the simultaneous nature of the actions.
Correct Sentence: The captain dropped the trophy while he was celebrating the victory…
Tense Rule:
· Use Past Continuous for an action that was ongoing in the past.
· Example: I was reading when the phone rang.
