Select the most appropriate option to fill in the blank.

Explanation :

The sentence describes two actions happening in the past:

1. The captain dropped the trophy (completed action)
2. He was celebrating (ongoing action at that time)

👉 So we use Past Continuous Tense for the ongoing action.

Grammar Rule:

When one action interrupts another in the past:

• Ongoing action → Past Continuous (was/were + verb-ing)
• Interrupting action → Simple Past

👉 Structure:
Subject + was/were + verb-ing

Correct Sentence:

The captain dropped the trophy while he was celebrating the victory with his teammates.

Option Analysis:

• celebrates → present tense ❌
• celebrated → simple past (not showing ongoing action) ❌
• was celebrating → ✔️ correct (past continuous)
• is celebrating → present continuous ❌
