D Correct answer
Explanation

Let Amit's age = A. Then Anubhav = 4A and Father = (4/5) of Anubhav = 5A. Sum: A + 4A + 5A = 160, giving 10A = 160, so A = 16 years. Father's age = 5A = 80 years. Difference between Father and Amit = 80 - 16 = 64 years. Express all ages in terms of one variable using the given relationships.
