Three of the following four letter-clusters are alike in a certain way and one is different. Find the odd one out.

Options

A. SWYBE
B. HKNQT
C. CFILO
D. QTWZC

Answer

A

Explanation

`"SWYBE" rarr S+4=W,W+2=Y,Y+3=B,B+3=E`. (using conversion table)
But `HKNQT" rarrH+3=K,K+3=N,N+3=Q,Q+3=T.
`CFILO`rarrC+3=F,F+3=I,I+3=L,L+3=O.
"QTWZC" rarrQ+3=T,T+3=W,W+3=Z,Z+3=C`.
Last three are in a pattern of three letter gap ,but letter in option does not follow it. So, option A is correct choice.
