A Correct answer
Explanation

A's efficiency is 50% more than B, so A's rate = 1.5 × (1/24) = 1/16. Combined rate = 1/24 + 1/16 = 5/48 work per day. Days needed = 48/5 = 9.6 days. Option D (16 days) is B's time alone, option C (6 days) would require faster workers, and option B (8 days) is too low.
