Sandwich pattern with shrinking middle – UGC NET Question

Outer letters move forward A,B,C,D → E. Inner double letters move backward Z,Y,X,W → V. So the next palindromic block is EVVE.

Option A:
Option A is correct because E is next outer letter and V is next inner letter (one step before W).

Option B:
Option B uses U, which is two steps before W, so it breaks the one-step backward movement.

Option C:
Option C breaks the palindromic structure (outer letters differ) and keeps W incorrectly.

Option D:
Option D jumps the inner letters back to X, reversing the backward sequence.
