B Correct answer
Explanation

Set up equations using work rates. Let m and w be work done by one man and one woman per day. From the two scenarios: (2m + w) × 14 = (2m + 4w) × 8. Solving gives 12m = 18w, so w = (2/3)m. Wages are proportional to work rates, so woman's daily wage = (2/3) × 90 = 60. Key insight: work rate ratio determines wage ratio.
