This question tests a term used to name a major artistic work, especially a musical composition. The word opus comes from Latin meaning “work” and is used in music to label a specific piece in a composer’s catalog, usually with a number that shows its place in publication or creation. This makes it the right choice because it directly identifies a defined, notable composition, rather than describing a quality or state.

For example, Beethoven’s Fifth Symphony is known as Opus 67, which clearly marks it as a distinct work in his output.

The other words describe qualities rather than refer to a specific work: convivial means sociable, exigent means urgent, and manifold means many or varied. They don’t denote a major artistic piece.
