What does 'invective' typically involve?

The term 'invective' describes a type of language that is particularly harsh, aggressive, or critical. It is often used in a rhetorical context to denounce or attack someone or something with strong, emotive words. Invective strives to convey contempt or strong disapproval, utilizing abusive or venomous language that can evoke a strong emotional response from the audience.

In contrast, the other options suggest positive or neutral forms of communication. Complimentary remarks, neutral observations, and supportive dialogues focus on praise, impartiality, or encouragement, which starkly differ from the hostile nature of invective. This makes option B the only choice that accurately captures the essence of what invective entails.
