The correct options are
A IREV D IRVEABCDEFGHIJKLMNOPQRSTUVWXYZ
We have to write down the alphabetical order and assign numbers to each alphabet.
MNZA
M and N are in the centre of the alphabetical order. On number 13&14
Z and A are the last and first letter of the alphabetical order.
LOYB
L and O are on the either side of M and N.
Y is before Z and B is after A.
KPXC
K and P are on the either side of L and O..
X is before Y and C is after B.
JQWD
J and Q are on the either side of K and P.
W is before X and D is after C.
?
We need letters that are on the either side of J and Q = IR
We need a letter before W and after D = VE
So the pattern suggests that the ? will be replaced by IRVE.
So option A is the wrong answer
Option D is the correct answer.
