D Correct answer
Explanation

Total work = 24 × 24 = 576 man-hours. If 72 men work: 576 ÷ 72 = 8 hours. The question asks for hours, but options are labeled 'days'. However, given the standard interpretation of such problems, option D (8 days/hours) is the intended answer assuming the unit is consistent.
