• B. When did he react?
• C. When did he reacted?
• D. When he reacted?

Answer 1

Answer:

B. When did he react?

The given sentence is:
"That was the moment when he reacted."
This is in the past tense, so the question must also be in the past tense.

Analysis of options:

• (A) When does he react? – ❌ Present tense; doesn't match the past tense of the response.

• ✅ (B) When did he react? – ✔️ Correct structure and tense.

• (C) When did he reacted? – ❌ Incorrect grammar. After "did", the verb should be in base form (react, not reacted).

• (D) When he reacted? – ❌ Not a grammatically correct question.
