C Correct answer
Explanation

Statement I: CI for 4 years is 107.36% of P. Using CI formula, we can find the rate. Statement II: SI for 2 years is Rs. 440, so P×R×2/100 = 440. Statement III: CI for 2 years is Rs. 484, giving another equation. With any two statements, we have two equations to solve for P and R. The claimed answer 'Any two' is correct because different pairs can solve for the principal.
