D Correct answer
Explanation

Total work = 24×8×18 = 3456 man-hours. Two-thirds of work = 3456×(2/3) = 2304 man-hours. 30 workers at 6 hours/day do 180 man-hours per day. Days needed = 2304/180 = 12.8 days. This uses the standard work formula: Work = Men×Hours×Days, and we solve for the unknown days when the work quantity and workforce parameters change.
