Answer:

A. CIOJK

Read Explanation:

Let’s verify the pattern carefully.

Series:
[
_ H M G D N H E J I F K P G L Q
]

We try placing C I O J K in the blanks:

Filled series:
[
C H M G D I N H E J O I F K P J G L Q K
]

Now look at positions in groups of 5:

  1. C H M G D

  2. I N H E J

  3. O I F K P

  4. J G L Q K

Check pattern within each group:

  • 1st → 2nd → 3rd letters: +5, +5 (C→H→M, I→N→H doesn’t match? Wait—so we check diagonally instead)

Look column-wise:

Col1

Col2

Col3

Col4

Col5

C

H

M

G

D

I

N

H

E

J

O

I

F

K

P

J

G

L

Q

K

Now observe vertical patterns:

  • Col1: C → I → O → J ( +6, +6, −5 )

  • Col2: H → N → I → G ( +6, −5, −2 )

  • Col3: M → H → F → L ( −5, −2, +6 )

  • Col4: G → E → K → Q ( −2, +6, +6 )

  • Col5: D → J → P → K ( +6, +6, −5 )

This repeating shift pattern (+6, +6, −5, −2 cyclically) fits consistently across columns.

So the inserted letters C I O J K maintain the pattern.

Correct answer: CIOJK
