C Correct answer
Explanation

Work = 2 persons * 3 days = 6 man-days. If only 1 person works, time = 6 man-days / 1 person = 6 days.

AI explanation

Using the formula for inverse proportionality, the total work is 2 persons multiplied by 3 days, which gives 6 man-days. With only 1 person working, the days required will be 6 man-days divided by 1 person, resulting in 6 days.
