C Correct answer
Explanation

Let Kamal's rate be k. Ehsaan's rate is 2k. Combined rate = 3k. 3k * 29 = 1 (total work). k = 1/87. Kamal takes 87 days.

AI explanation

Because Ehsaan is twice as efficient as Kamal, Ehsaan does two-thirds of the work and Kamal does one-third while working together. Their combined rate finishes the job in 29 days, meaning Kamal's share of the work would take him 29 multiplied by 3, which equals 87 days to complete alone.
