D Correct answer
Explanation

Let the son's current age be x. Father's current age is 5x. Three years back, son was x-3 and father was 5x-3. Since father was 24 years older than son three years back: 5x-3 = x-3+24, which gives 4x=24, so x=6. Son is currently 6, so three years from now he will be 9 years old.
