D Correct answer
Explanation

Simple Interest = P × R × T = 2880 × 0.10 × 3 = Rs. 864. Compound Interest = P(1 + r)^t - P = 2880(1.1)³ - 2880 = 2880 × 1.331 - 2880 = 3833.28 - 2880 = Rs. 953.28. Difference = 953.28 - 864 = Rs. 89.28. The difference grows each year as compound interest earns interest on interest.
