B Correct answer
Explanation

6 years ago, average age of Kishore, wife, and child was 38 years, so their sum was 114 years. Presently, their sum is 114 + 18 = 132 years (adding 6 years for each of the 3 people). 8 years ago, wife and child's average was 32 years, so their sum was 64 years. Presently, their sum is 64 + 16 = 80 years (adding 8 years for each of the 2 people). Therefore, Kishore's present age = 132 - 80 = 52 years.
