Step 1: Understand the pairs
- In criminal cases, the party bringing the case is the \textit{prosecution} and the person charged is the \textit{accused}.
- In civil cases, the party initiating the case is the \textit{plaintiff} and the person against whom the case is brought is the \textit{defendant}.
Step 2: Matching the analogy
- Prosecution : Accused :: Plaintiff : Defendant
Hence, option (B) Plaintiff is correct.
