C Correct answer
Explanation

Simple interest = P × R × T = 303.60, where R = 4% = 0.04, T = 3. So P = 303.60 / (0.04 × 3) = 2530. Compound interest = 2530 × (1 + 0.04)^3 - 2530 = 2530 × 1.124864 - 2530 = 315.90. The difference between CI and SI arises because CI earns interest on accumulated interest.
