B Correct answer
Explanation

Given Rohit:Rina = 1:3, let Rohit = x, Rina = 3x. Method 1 (III alone): Difference Rina - Rohit = 13, so 3x - x = 13, 2x = 13, x = 6.5. Rina = 19.5 years. Method 2 (I and II): Pooja - Rohit = 11, and Pooja = 3×Rohit - 2. So 3x - 2 - x = 11, 2x = 13, x = 6.5. Rina = 19.5 years. Either method gives same answer. Option B is correct.
