In the given letter-cluster pairs, the first letter-cluster is related to the second letter-cluster following a certain logic. Study the given pairs carefully, and from the given options, select the pair that follows the same logic.
PARTS : RDVYY
CLOSE : EOSXK

Correct option is C

Given:

letter-cluster pairs

PARTS : RDVYY
CLOSE : EOSXK

Logic: The first letter is shifted forward by 2 positions, The second letter is shifted forward by 3 positions, The third letter is shifted forward by 4 positions,

The fourth letter is shifted forward by 5 positions, The fifth letter is shifted forward by 6 positions.

PARTS : RDVYY

P+2=R, A+3=D, R+4=V, T+5=Y, S+6=Y   

CLOSE : EOSXK

C+2=E, L+3=O, O+4=S, S+5=X, E+6=K

Similarly,

​RHINO : TKMSU

R+2=T, H+3=K, I+4=M, N+5=S, O+6=U

RHINO : TKMSU, is the correct answer.

Thus correct option is (c)
