B Correct answer
Explanation

Let son's present age be x years. Father's present age = x + 26 years. After 3 years: son will be (x + 3) and father will be (x + 29). Given: x + 29 = 3(x + 3). Solving: x + 29 = 3x + 9, so 20 = 2x, thus x = 10. Son's present age is 10 years, so father's present age is 10 + 26 = 36 years.
