Sonata Form is distinguished by its three main sections: exposition, development, and recapitulation. This structure allows composers to present and explore contrasting themes and key areas in a systematic way. In the exposition, the primary themes are introduced; the development section manipulates and transforms these themes, often modulating to different keys; and the recapitulation revisits the original themes, bringing them back to the home key. This form is prevalent in many works from the Classical period, particularly in symphonies and sonatas.

Binary Form, Rondo Form, and Theme and Variations each have their own characteristics. Binary Form consists of two contrasting sections that are often repeated, while Rondo Form typically features a recurring main theme alternating with contrasting episodes. Theme and Variations involves presenting a theme followed by several variations that alter the initial theme in various ways. These forms do not incorporate the same structured approach of exposition, development, and recapitulation found in Sonata Form, making it the correct answer to the question.
