Which of the following options should come in place of the question mark (?) in the given series based on the English alphabetical order? YTL, QLD, IDV, AVN,?
SNF
SNG
SMG
SMF
SNF
Look at each position independently: 1st letter moves -8 (Y to Q is -8, Q to I is -8, I to A is -8, A - 8 is S); 2nd letter moves -3 (T to Q is -3, Q to D is -13/13-10? No: T(20) → Q(17) is -3, Q(17) → D(4) is -13, D(4) → N(14) is +10... let's re-verify). Actually: YTL, QLD, IDV, AVN. 1st: Y(25), Q(17), I(9), A(1) → -8 steps. 2nd: T(20), L(12), D(4), V(22) → -8 steps. 3rd: L(12), D(4), V(22), N(14) → -8 steps.

Analyze 1st Letters
Y(25), Q(17), I(9), A(1). Pattern: -8. Next: A(1) - 8 = S(19).
Analyze 2nd Letters
T(20), L(12), D(4), V(22). Pattern: -8. Next: V(22) - 8 = N(14).
Analyze 3rd Letters
L(12), D(4), V(22), N(14). Pattern: -8. Next: N(14) - 8 = F(6).
B: SNG ends in G instead of F. C: SMG uses M and G. D: SMF uses M instead of N.
A is correct because every letter in each triplet shifts back by 8 positions in the alphabet sequence to produce the next triplet (Y-8=Q, T-8=L, L-8=D; Q-8=I, L-8=D, D-8=V; I-8=A, D-8=V, V-8=N; A-8=S, V-8=N, N-8=F).
For long-string series, always analyze letter-by-letter vertical columns (1st, 2nd, 3rd positions) separately to identify the underlying shift pattern.
