Which term describes work that conforms to recognized rules?

The term that describes work conforming to recognized rules is "canonical." This word indicates that a certain standard or set of guidelines has been established and followed, representing what is widely accepted as authoritative or traditional within a particular field or discipline. For example, in literature, canonical works are those that are considered essential reading because they adhere to established literary conventions and have significant cultural or academic impact.

The other terms do not convey this meaning. "Innovative" suggests originality and new ideas that break from tradition, "spontaneous" implies actions or works that occur without planning or premeditation, and "radical" indicates a departure from the norm, often advocating for extreme changes or ideas. None of these options aligns with the definition of adhering to recognized rules like "canonical" does.
