B Correct answer
Explanation

For compound interest: A = P(1 + r/100)ⁿ. Given A = Rs. 2916, r = 8%, n = 2 years. So 2916 = P(1.08)² = P × 1.1664, giving P = 2916/1.1664 = Rs. 2500. For simple interest at 9% for 3 years on Rs. 2500: SI = 2500 × 9 × 3 / 100 = Rs. 675. Option A requires principal Rs. 2500 at 8%, Option C would need Rs. 2500 at 8.67%, and Option D is a calculation error.
