Who is described as the Defendant in a lawsuit?

In a lawsuit, the Defendant is the party who is alleged to have committed a wrong. This designation is key in legal proceedings, as it pertains to the individual or entity that faces allegations brought forth by the Plaintiff, who is the party initiating the lawsuit. The Defendant's role in the legal process is to respond to these allegations and defend against the claims made, thereby engaging in what is often a process of dispute resolution before the court.

The other options do not accurately define the Defendant's role. The party who initiates the lawsuit refers to the Plaintiff, while the description of representing the interests of a minor pertains typically to a guardian or representative, not the Defendant. Lastly, the collection of evidence can be conducted by various parties involved in the case but is not specific to the role of the Defendant. Thus, B is indeed the accurate description of the Defendant in this context.
