D Correct answer
Explanation

Profit is distributed in proportion to capital × time. A invested Rs. 80000 for 36 months = 28,80,000 units. B joined after 6 months, so invested Rs. 90000 for 30 months = 27,00,000 units. Ratio A:B = 2880:2700 = 16:15. B's share = 15/(16+15) × 21700 = 15/31 × 21700 = 10500.
