Find the odd letter group: BCD, MNO, KLM, PQR.

ABCD

BMNO ✓ Correct

CKLM

DPQR

Correct answer: (B) MNO

Explanation

MNO is the odd group.

BCD, MNO, KLM and PQR are each three consecutive letters.

So the consecutive pattern does not separate them.

BCD, KLM and PQR contain only consonants.

MNO holds the vowel O, so it stands apart.
