Option a:
# = IPD, % = OET
I + 2 = K
P - 2 = N
D + 2 = F
Similarly,
Q - 2 = O
C + 2 = E
V - 2 = T
As there is no same pattern between right side and left side. So, option (a) is incorrect.
Option b:
# = HPD, % = NFS
H + 3 = K
P - 2 = N
D + 2 = F
Similarly,
Q - 3 = N
C + 3 = F
V - 3 = S
As there is no same pattern between right side and left side. So, option (b) is incorrect.
Option c:
# = MLH, % = OET
M - 2 = K
L + 2 = N
H - 2 = F
Similarly,
Q - 2 = O
C + 2 = E
V - 2 = T
As there is same pattern between right side and left side. So, option (c) is correct.
Option d:
# = HQC, % = NFS
H + 3 = K
Q - 3 = N
C +3 = F
Similarly,
Q - 3 = N
C + 3 = F
V - 3 = S
As there is no same pattern between right side and left side. So, option (d) is incorrect.
