B Correct answer
Explanation

Let monthly incomes of A, B, C be 2x, 3x, 5x respectively. Given C's monthly income exceeds A's by Rs. 1500: 5x - 2x = 1500, so 3x = 1500, which means x = 500. B's monthly income = 3x = 3 × 500 = Rs. 1500. B's annual income = 1500 × 12 = Rs. 18,000. Note: Option C shows Rs. 1500, which is B's monthly income, not annual - this is a distractor.
