B Correct answer
Explanation

Total work is 3 men * 6 days = 18 man-days. After 2 days, 3 men have done 6 man-days of work, leaving 12 man-days. With 3 more men (total 6), the remaining work takes 12 / 6 = 2 days.

AI explanation

The total work is 3 men multiplied by 6 days, giving 18 man-days. In the first 2 days, 3 men complete 6 man-days, leaving 12 man-days of work. When 3 more men join, the total strength becomes 6 men, so the remaining 12 man-days divided by 6 men yields 2 days to complete the work.
