A,B,C Correct answer
Explanation

Let the son's age be AB (two digits), then father's age is BA. So (10A+B) + (10B+A) = 66, meaning 11(A+B) = 66, so A+B = 6. Valid pairs where father > son: (0,6), (1,5), (2,4). This gives ages 60 and 06, 51 and 15, 42 and 24. The option 82 and 28 sums to 110, not 66.
