A, B, C,  D and E have different ages. C is older than B but younger than D. Only one person is younger than A. B is not the youngest. Who amongst them is the second oldest?

Given:

A, B, C, D and E have different ages.

C is older than B but younger than D.

Only one person is younger than A.

B is not the youngest.

E < A < B < C < D

So, the second oldest is: C

Thus, correct option is (d).
