WTQ
- B.
YVS
- C.
TQN
- D.
FCB
Show answer & explanation
Correct answer: D
Concept: In a letter-classification (odd-one-out) question, every set of letters is checked against a single alphabetical-position rule — the fixed number of places the alphabet position drops (or rises) from one letter to the next within the set. Three of the four sets share the exact same rule; the set that breaks it, even in just one step, is the odd one out.
Application: Converting every letter to its alphabet position and checking the gap between consecutive letters in each set:
Set | Letters (alphabet position) | Gap 1 | Gap 2 |
|---|---|---|---|
WTQ | W(23) → T(20) → Q(17) | -3 | -3 |
YVS | Y(25) → V(22) → S(19) | -3 | -3 |
TQN | T(20) → Q(17) → N(14) | -3 | -3 |
FCB | F(6) → C(3) → B(2) | -3 | -1 |
Cross-check: Applying the same "-3, -3" rule that WTQ, YVS, and TQN all follow to the fourth set gives F(6) - 3 = C(3), which matches — but then C(3) - 3 = 0, which is not a valid alphabet position. The actual next letter is B(2), only 1 place back, not 3. This independently confirms the FCB set does not fit the shared rule the other three sets follow.
Therefore, FCB is the odd letters set among the given alternatives.
