E Correct answer
Explanation

Statement I gives Alok:Vipul = 2:3, so Alok = (2/3)Vipul. Statement II gives Vipul = Alok + 6. Neither alone is sufficient - I needs Vipul's age, II needs a relationship. Together: Substitute II in I: Alok = (2/3)(Alok+6), so 3Alok = 2Alok + 12, giving Alok = 12. After 4 years = 16. Both needed, so option E is correct.
