C Correct answer
Explanation

Let the son's present age be x years. Then Pankaj's present age is 4x years. After 10 years: Pankaj's age = 4x + 10, son's age = x + 10. Given that Pankaj's age will be twice his son's age: 4x + 10 = 2(x + 10). Solving: 4x + 10 = 2x + 20 → 2x = 10 → x = 5. The son's present age is 5 years.
