Correct option is C
Given: To solve this analogy, we need to understand the pattern or rule that relates the first pair of letter clusters (SPEAK : ROIEJ) and the second pair (THEIR : SGIOQ). Once we determine this pattern, we can apply it to find the correct answer.
Let's break down each pair to identify the relationship:

Vowels series: A, E, I , O, U
Concept: vowels are taken one step forward as per the vowel series given.
Consonants are taken one step backward as per alphabetical series.

Option c is the correct answer.
