D Correct answer
Explanation

Average age of father and son is 22 years, so their total age is 44 years. Given the ratio 10:1, let son's age be x, then father's age is 10x. So x + 10x = 44, giving 11x = 44, so x = 4. Therefore son's age is 4 years and father's age is 40 years. Option D (4) is correct.
