C Correct answer
Explanation

6 women do work in 3 days, so 1 woman takes 18 days. 3 women + 18 children take 2 days. Work rate: 3/18 + 18/(child's rate) = 1/2. So 1/6 + 18/c = 1/2, giving 18/c = 1/3, so c = 54. One child takes 54 days. 9 children together take 54/9 = 6 days. Option C is correct. Options A, B, D are incorrect calculations.
