Which of the following describes a behavior that conforms to social norms?

Propriety refers to the state of conforming to accepted standards of behavior, manners, or morality within a social context. This quality encompasses a respect for social norms and expectations, making it synonymous with behaving appropriately in a given situation. When someone acts with propriety, they are adhering to the norms of conduct that society has established, whether in formal settings like a wedding or informal gatherings among friends.

In contrast, the other options do not reflect this notion of conforming to social norms. Eclectic suggests a varied or diverse approach that does not necessarily align with a specific norm. Elucidate means to clarify or make something clear, which is unrelated to behavior. Jeer, on the other hand, means to mock or ridicule and often involves behavior that flouts social conventions rather than adhering to them. Thus, propriety stands out as the term that embodies conformity to social norms.
