Correct Answer - Option 4 : JQDKB
Given,
LOGIC : BHFNK :: CLERK : ?
The pattern followed here is,
L - 1 = K,
O - 1 = N,
G - 1 = F,
I - 1 = H,
C - 1 = B
and these letters are written in reverse order as BHFNK,
Similarly,
C - 1 = B,
L - 1 = K,
E - 1 = D,
R - 1 = Q,
K - 1 = J
and these letters are written in reverse order as JQDKB,
Hence, the correct answer is JQDKB.
