B Correct answer
Explanation

If 60% is done in 6 days, 10% is done in 1 day. The remaining 40% takes 4 days.

AI explanation

Since the worker completes 60 percent of the job in 6 days, the total time required to finish the entire 100 percent of the job alone is 6 divided by 0.60, which equals 10 days. This leaves 40 percent of the job remaining to be done. Multiplying the 40 percent remaining (0.40) by the total time of 10 days gives 4 more days needed to complete the work.
