B Correct answer
Explanation

Work is inversely proportional to the number of workers. 1 worker * 206 days = 4 workers * x days. x = 206 / 4 = 51.5 days.

AI explanation

Since the total work requires 206 worker-days, dividing this total work by 4 workers gives the required time. Calculating 206 / 4 yields 51.5 days.
