B Correct answer
Explanation

This is an inverse proportion problem. 4 men * 16 days = 8 men * X days. 64 = 8X, so X = 8.

AI explanation

Using the work formula (Men1 * Days1) = (Men2 * Days2), we substitute the given values to get 4 * 16 = 8 * D. Solving for D gives 64 = 8D, which means D = 8 days.
