D Correct answer
Explanation

5 women complete work in 119 days, so total work = 5 × 119 = 595 woman-days. If 10 men take same time, 10 × 119 = 1190 man-days = 595 woman-days, so 1 man = 0.5 woman. Combined rate: 5 women + 4 men = 5 + (4 × 0.5) = 7 women equivalent. Days = 595 ÷ 7 = 85. Option D is correct.
