Answer 1

The Correct Option is A

1. Option A: Active, direct, and preserves the original sequence and meaning.
2. Option B: Stays passive and is more roundabout than needed.
3. Option C: Forces an inverted "no sooner...than" construction unnecessarily.
4. Option D: Forces an inverted "hardly had...than" construction with a non-standard comma.

The clearest, most natural option is A, so the correct answer is Option A.
