B Correct answer
Explanation

Wages are distributed in the ratio of work done. If A does it in 9 days and B in 15, their rates are 1/9 and 1/15. The ratio of their rates is (1/9) : (1/15) = 15 : 9 = 5 : 3.

AI explanation

Wages are distributed in the ratio of the one day work done by each person. A's one day work is 1/9 and B's one day work is 1/15, making their efficiency ratio 1/9 : 1/15. By multiplying by the least common multiple of 45, this ratio becomes 5 : 3.
