What should come in place of? in the given series based on the English alphabetical order?
WAP, VEO, UIN, TMM, ?

Correct option is C

Given Series: WAP, VEO, UIN, TMM, ?
Logic: 1st -1, 2nd +4 and3rd - 1 

1st Letter (W, V, U, T, ?):
W → V: W - 1 = V
V → U: V - 1 = U
U → T: U - 1 = T
So, the next letter should be S: T - 1 = S
2nd Letter (A, E, I, M, ?):
A → E: A + 4 = E
E → I: E + 4 = I
I → M: I + 4 = M
So, the next letter should be Q: M + 4 = Q
3rd Letter (P, O, N, M, ?):
P → O: P - 1 = O
O → N: O - 1 = N
N → M: N - 1 = M
So, the next letter should be L: M - 1 = L
Thus, the correct answer is (C) SQL.
