B Correct answer
Explanation

Let the son's present age be x years. Then mother's age is 5x years. After 4 years: (x + 4) + (5x + 4) = 44. Solving: 6x + 8 = 44, so 6x = 36, giving x = 6. The son is currently 6 years old and the mother is 30 years old. After 4 years, they will be 10 and 34, summing to 44.
