Find the odd number / letters / word from the given alternative:

SUNDAY : NSVYDB
MOTHER : TMPRHD
SIMPLE : MSJEPM
MOSTLY : SMPYTM E. SIMPLE : MSJEPM

The answer is D. MOSTLY : SMPYTM.

For example, in SUNDAY, the letters are S, U, N, D, A, Y, but in NSVYDB, the letters are N, S, V, Y, D, B, A. The same is true for MOTHER and TMPRHD, and for SIMPLE and MSJEPM. However, in MOSTLY, the letters are M, O, S, T, L, Y, but in SMPYTM, the letters are S, M, P, Y, T, M. The letter “O” is missing.
