Concept:
These questions involve rearrangement of letters. Check how the second word is formed from the first.
Step 1: Analyze Option (A).
ASTRO → AOTSR
Pattern: First letter same, remaining letters rearranged.
Step 2: Analyze Option (C).
GROUP → OURPG
Pattern: Letters rearranged in a consistent shifting pattern.
Step 3: Analyze Option (D).
APICET → AEITPC
Pattern: Letters rearranged systematically.
Step 4: Analyze Option (B).
THRIVE → EIVRTH
This is a complete reverse of the word:
\[
THRIVE \rightarrow EVI RHT \neq EIVRTH
\]
The pattern does not match others.
Hence, (B) does not follow the same rearrangement pattern.
