Correct Answer: ABCD

The logical order is chronological: Fleming's return and the mould on the dish (A), his observation that the surrounding bacteria had been destroyed (B), the conclusion that this led to penicillin's discovery (C), and the later development into a usable drug (D). Hence the sequence ABCD.
