A Correct answer
Explanation

Let Naimish's present age be N and Deepak's present age be D. Given N = D - 8. Four years hence: (N + 4)/(D + 4) = 4/5. Cross-multiply: 5N + 20 = 4D + 16. Substitute N = D - 8: 5(D - 8) + 20 = 4D + 16. This gives 5D - 40 + 20 = 4D + 16, so D = 36. Therefore N = 36 - 8 = 28. Option A is correct.
