C Correct answer
Explanation

Work = M1 * D1 * H1 = M2 * D2 * H2. 10 * 12 * 7 = 14 * D2 * 6. 840 = 84 * D2. D2 = 10.

AI explanation

Using the Man-Days-Hours formula, M1 * D1 * H1 = M2 * D2 * H2. Substituting the given values results in 10 * 12 * 7 = 14 * D2 * 6. Solving this equation yields 840 = 84 * D2, which simplifies to 10 days.
