- The present ages of A and B have a ratio of 8:9, denoted by 8x and 9x, respectively.

- In 9 years, their ages will be (8x + 9) and (9x + 9), respectively.

- At that time, the ratio of their ages will be 19:21.

- The equation is: (8x + 9) / (9x + 9) = 19 / 21.

- Solving the equation yields x = 6.

- Therefore, B's present age is 9x = 54 years.

- C is 3 years younger than B, so C's age is 51 years.

- Thus, the correct answer is Option 3: 51.
