WTQ : DGJ :: NKH : ?

Expression = WTQ : DGJ

The pattern followed is that there are as many alphabets to the left of the first letter as there are to the right of the leftmost letter in right hand side

W is 23th from left end and D is 23th from right end. T is 20th from left end and G is 20th from right end. Finally, Q is 17th from left end and J is 17th from right end in English alphabetical series.

Similarly, for NKH :

Now, N is 14th from left end, thus first letter will be 14th from right end = M

K is 11th from left end, second letter will be 11th from right end = P

H is 8th from left end, third letter will be 8th from right end = S

Thus, missing term = MPS

=> Ans - (A)
