B Correct answer
Explanation

Principal = 9600, Time = 2.5 years, Rate = 9%. Simple Interest = (P * R * T) / 100 = (9600 * 9 * 2.5) / 100 = 96 * 22.5 = 2160. Amount = 9600 + 2160 = 11760.

AI explanation

Convert 2 and a half years to 5/2 years and apply the simple interest formula, giving I = (9600 * 9 * 5/2) / 100. This calculation yields an interest of Rs.2160. The total amount to be paid back is the principal plus the interest, so 9600 + 2160 = Rs.11,760.
