Final answer:
The characteristic 'Be Irrelevant' does not align with any Gricean Maxims, as they all promote effective communication, and being irrelevant would contradict the Maxim of Relation.
Step-by-step explanation:
The Gricean Maxims are a set of conversational rules proposed by philosopher H. Paul Grice. These maxims are intended to guide effective and efficient communication. The four Gricean Maxims include the Maxim of Quality, which implores individuals to tell the truth; the Maxim of Quantity, advising speakers to be informative and provide the right amount of information; the Maxim of Relation, which encourages people to be relevant; and the Maxim of Manner, which suggests communicators should be clear, avoiding ambiguity while being brief and to the point. Considering the attributes of these maxims, the characteristic of being 'Irrelevant' (C) is not advocated by any of them; in fact, it directly contradicts the Maxim of Relation.
