Answer: (2) 14 years

Explanation:-
The average of man and his son = 28 years
Then, the sum of the age of a man and his son = 2 x 28
= 56 years

Six years hence the sum of their ages = 56 + 2 x 6
= 56 + 12 = 68 years

Six years hence the ratio of their age becomes 12: 5

Then, the age of his son = 68 x 5/17
= 4 x 5
= 20 years

So, the present age of his son = 20 – 6
= 14 years

Hence, the correct answer is option (2) 14 years.
