B Correct answer
Explanation

Sambhu does the whole work in 16 days (1/2 in 8 days). Kalu does the whole work in 18 days (1/3 in 6 days). Their combined rate is 1/16 + 1/18 = (9+8)/144 = 17/144. Time taken is 144/17 days.

AI explanation

Sambhu completes the work in 16 days and Kalu completes it in 18 days. Using the Least Common Multiple method, assume the total work is 144 units, making their daily work units 9 and 8 respectively. Working together, their combined daily output is 17 units. Therefore, they will complete the entire work in 144/17 days.
