Select the option that is related to the fifth letter cluster in the same way as the second letter cluster is related to the first letter cluster and the fourth letter cluster is related to the third letter cluster.

RJCZ : KPVF :: DJVE : WPOK :: PGCS : ?

Given: RJCZ : KPVF :: DJVE : WPOK :: PGCS : ?

Logic: Subtract 7 and add 6 alternately to the place values of the letters of the given letter clusters to get their required letter clusters.

Explanation:
RJCZ $$\rightarrow$$ R - 7 = K; J + 6 = P; C - 7 = V; Z + 6 = F

So, RJCZ is related to KPVF.

DJVE $$\rightarrow$$ D - 7 = W; J + 6 = P; V - 7 = O; E + 6 = K

So, DJVE is related to WPOK.

Similarly, follow the same pattern for PGCS $$\rightarrow$$ P - 7 = I; G + 6 = M; C - 7 = V; S + 6 = Y

Thus, the correct answer is option (c).
