A Correct answer
Explanation

Each statement independently provides enough information to calculate the total work in man-days. From statement I: 12 men do 4/5 work in 24 days, so total work = 12 × 24 × 5/4 = 360 man-days. 18 men would take 360/18 = 20 days. Statements II and III give the same result (360 man-days).
