D Correct answer
Explanation

Statement I relates woman's efficiency to man's, Statement II relates woman's to child's. Neither gives absolute work rate or total work. We need total work amount or base efficiency to calculate number of women. Even together, we only have relative efficiencies without knowing total work or any absolute rate, so the question cannot be answered.
