Three of the following four letter-clusters are alike in a certain way and one is different. Find the odd one out.
$$KMPT\longrightarrow\ K+2=M,M+3=P,P+4=T.$$ (by using conversion table)
$$OQSV\longrightarrow\ O+2=Q,Q+2=S,S+3=V.$$
$$QSVZ\longrightarrow\ Q+2=S,S+3=V,V+4=Z.$$
$$EGJN\longrightarrow\ E+2=G,G+3=J,J+4=N.$$
So, option B is correct choice.
