B Correct answer
Explanation

Work rate of A+B = 1/16. Work rate of A = 1/24. Work rate of B = 1/16 - 1/24 = (3-2)/48 = 1/48. B takes 48 days.

AI explanation

Using the formula for combined work, (A and B)'s rate is 1/16 and A's rate is 1/24. B's rate is (1/16) - (1/24) = (3 - 2) / 48 = 1/48. Therefore, B alone can complete the work in 48 days.
