The correct option is
B ZEJQBKD
The pattern followed by these words is :
R +1→ S, E −1→ D, S +1→ T, P −1→ O, O +1→ P, N −1→ M, D +1→ E.
So, the group of letters obtained is SDTOPME.
Reverse the above group of letters and get the code.
Thus, RESPOND is coded as EMPOTDS.
Same for the word SENSE.
Let us follow the same pattern for CLARIFY,
C+1→ D, L−1→ K, A+1→ B, R−1→ Q, I+1→ J, F−1→ E, Y+1→ Z
The group of letters obtained is DKBQJEZ.
Hence, the code for CLARIFY is 'ZEJQBKD'.
