Final answer:
In libel law, the libelous material must contain defamatory language. This asserts an untrue fact that would cause harm to the plaintiffs reputation in the mind of "right thinking persons." Option A is correct.
Step-by-step explanation:
In libel law, defamatory language refers to false statements that harm someone's reputation. For a statement to be legally considered libelous, it must meet specific criteria. Firstly, the statement must be false, as truth is a defense against defamation claims. Secondly, the false statement must cause harm or damage the reputation of the individual or entity it refers to. This harm could include financial losses, damage to one's professional reputation, or personal distress. Additionally, the statement must be published or communicated to a third party. Lastly, there should be a level of negligence or intentionality in publishing the false statement.
Furthermore, to be actionable, the statement should be one that a reasonable person would believe to be true. This aspect is crucial as it determines the impact on the plaintiff's reputation. Therefore, the libelous material must contain defamatory language that asserts an untrue fact causing harm to the plaintiff's reputation in the mind of "right thinking persons."
