Select the option that is related to the fifth letter-cluster in the same way as the second letter-cluster is related to the first letter-cluster and the fourth letter-cluster is related to the third letter-cluster.
SPEAK : ROIEJ :: THEIR : SGIOQ :: BEING : ?

Let's analyze the pattern for the first pair: SPEAK → ROIEJ
Consonants and Vowels might follow different rules:

S (Consonant)
−1

​
R

P (Consonant)
−1

​
O

E (Vowel) → next vowel is I (Vowels sequence: A,E,I,O,U)

A (Vowel) → next vowel is E

K (Consonant)
−1

​
J

Let's test this logic with the second pair: THEIR → SGIOQ

T (Consonant)
−1

​
S

H (Consonant)
−1

​
G

E (Vowel) → next vowel is I

I (Vowel) → next vowel is O

R (Consonant)
−1

​
Q

The rule is confirmed:

Consonants are shifted by −1.

Vowels change to the immediate next vowel in the sequence A→E→I→O→U→A.

Applying this rule to BEING:

B (Consonant)
−1

​
A

E (Vowel) → next vowel is I

I (Vowel) → next vowel is O

N (Consonant)
−1

​
M

G (Consonant)
−1

​
F

The resulting code cluster is AIOMF.
