B Correct answer
Explanation

Let son's current age be S. Father's current age F = 36. When son was born (S years ago), father's age was F - S. According to the problem, F - S = S + 2. Substituting F = 36: 36 - S = S + 2, which gives 2S = 34, so S = 17. The son's current age is 17, therefore 5 years ago he was 17 - 5 = 12 years old. Option B is correct.
