B Correct answer
Explanation

Let current ages be J (Jayant) and P (Puneet). 8 years ago: J - 8 = 3(P - 8), so J = 3P - 16. 8 years from now: J + 8 = 2(P + 8), so J = 2P + 8. Equating: 3P - 16 = 2P + 8, giving P = 24. Then J = 3(24) - 16 = 56. 4 years ago: Jayant was 52, Puneet was 20. Ratio = 52:20 = 13:5. Option B is correct.
