BDFH : YWUS :: JLNP : ?

Expression = BDFH : YWUS

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

B is the second letter and Y is the second last, D is 4th from left end and W is 4th from right end. F is 6th from left end and U is 5th from right end. Finally, H is 8th from left end and S is 8th from right end in English alphabetical series.

Similarly, for JLNP :

Now, J is 10th from left end, thus first letter will be 10th from right end = Q

L is 12th from left end, second letter will be 12th from right end = O

N is 14th from left end, third letter will be 14th from right end = M

P is 16th from left end, third letter will be 16th from right end = K

Thus, missing term = QOMK

=> Ans - (A)
