B Correct answer
Explanation

Let present ages be 2x and x. After 5 years: (2x+5)/(x+5) = 3/2. Cross-multiplying: 4x+10 = 3x+15, so x = 5. Present ages are 10 and 5 years. Option A (40, 20) and D (20, 10) are proportional but don't satisfy the 5-year condition. Option C's values are not in 2:1 ratio.
