- Let's denote B's income as Rs. 100x.

- A's income is 45% more than B's. So, A's income = Rs. 145x.

- The sum of A's and B's incomes = Rs. 145x + 100x = Rs. 245x.

- C's income is 60% less than the sum of A's and B's incomes: C = 40% of 245x = Rs. 98x.

- D's income is 20% more than C's: D = Rs. 1.2 * 98x = Rs. 117.6x.

- The difference between B's and D's income is Rs. 13200: Rs. (117.6x - 100x) = Rs. 17.6x = Rs. 13200.

- Solving for x: 17.6x = 13200; x = 750.

- C’s income = Rs. 98x = Rs. 73500.

- Option 3: 73500 is the correct answer.
