Given: The ratio of age of Krish and her mother is 5:12 and difference of their ages is 21.

Let the age of Krish be 5x and the age of her mother be 12x.

Then, 12x - 5x = 21

Solving for x, we get x = 3.

So, Krish's age = 5x = 15 years and her mother's age = 12x = 36 years.

After 3 years, Krish's age will be 18 years and her mother's age will be 39 years.

Therefore, the required ratio of their ages after 3 years = 18:39 = 6:13.

Hence, the correct answer is option D) 6:13.
