B Correct answer
Explanation

Total work = 12 * 18 = 216 man-days. After 6 days, 12 * 6 = 72 man-days are done. Remaining work = 216 - 72 = 144 man-days. Remaining men = 12 - 4 = 8. Days required = 144 / 8 = 18 days.

AI explanation

The total work is 12 men multiplied by 18 days, which equals 216 man-days. The work done in the first 6 days is 12 men multiplied by 6 days, equaling 72 man-days, leaving 144 man-days of work. The remaining 8 men will take 144 man-days divided by 8 men, which equals 18 days.
