B Correct answer
Explanation

Using M1 * D1 = M2 * D2, 2 * 8 = M2 * 4. 16 = 4 * M2, so M2 = 4.

AI explanation

Using the formula M1D1 = M2D2, we substitute the given values to get 2 men multiplied by 8 days equals the required men multiplied by 4 days. This simplifies to 16 = 4 multiplied by the required men. Dividing both sides by 4 gives the required number of men as 4.
