Select the pair that follows the same pattern as that followed by the two pairs given below. Both pairs follow the same pattern.

QRU : NTS

KVQ : HXO

Logic: first letter is decreasing by 3, second letter is increasing by 2 and third letter is decreasing by 2.

As,

QRU : NTS

Q-3=N, R+2=T, U-2=S

and

KVQ : HXO

K-3=H, V+2=X, Q-2=O

Now,

Check option (a), EZM : BBK

E-3=B, Z+2=B, M-2=K

Check option (b), KAQ : HCT

K-3=H, A+2=X, Q+3=T

So, its not correct.

Check option (c), SMY : QNX

S-2=Q, M+1=N, Y-1=X

​ So, its not correct.

Check option (d), ​WKA : ULZ

W-2=U, K+1=L, A-1=Z

So, its not correct.
