C Correct answer
Explanation

Ross: SI = 7000 * 0.05 * 2 = 700. Rashmi: CI = 5000 * (1.08^2 - 1) = 5000 * (1.1664 - 1) = 5000 * 0.1664 = 832. Difference = 832 - 700 = 132.

AI explanation

Ross earns simple interest calculated as (7000 * 5 * 2) / 100 = Rs. 700. Rashmi earns compound interest calculated by finding the total amount using A = P(1 + R/100)^T, which gives 5000(1 + 0.08)^2 = 5000(1.1664) = Rs. 5832. Rashmi's compound interest is the total amount minus the principal, equalling 5832 - 5000 = Rs. 832. The difference between their interests is 832 - 700 = Rs. 132.
