C Correct answer
Explanation

A and B invest in ratio 9:7, so total investment parts = 16. After 10% charity deduction, 90% of profit is distributed in the 9:7 ratio. B's share = (7/16) × 90% of total profit = (7/16) × 0.9 × P = 1260. Solving: P = 1260 × 16 / (7 × 0.9) = 1260 × 16 / 6.3 = 3200. Option C is correct.
