Which of the following correctly describes the Recapitulation section of the Sonata Allegro form?

The Recapitulation section of the Sonata Allegro form is characterized by the return of both the primary themes presented in the Exposition, but this time they are restated in the original tonic key. This is significant because it provides a sense of closure and resolution after the often more complex and wandering Development section.

By restating the themes in the tonic key, the Recapitulation reinforces the main ideas of the piece and brings the listener back to the familiar thematic material. This section serves as a way to unify the musical structure, ensuring that the listener recognizes the main themes as they reappear, solidifying the tonal foundation of the piece.

In contrast, other sections of the Sonata form play different roles: the Exposition introduces the themes, the Development explores and varies them, and the Recapitulation ultimately resolves and reiterates them in the home key.
