C Correct answer
Explanation

Principal = 8000, Rate = 15%, Time = 3 years. Amount after 1 year = 8000 × 1.15 = 9200. After 2 years = 9200 × 1.15 = 10580. After 3 years = 10580 × 1.15 = 12167. CI = 12167 - 8000 = Rs 4167. Option C is correct. Alternatively: CI = P[(1 + r/100)³ - 1] = 8000[1.15³ - 1] = 8000 × 0.520875 = Rs 4167.
