Which form structures a musical piece with alternating sections that create contrast and includes a recurring section A?

The correct answer is B, as the Rondo form is characterized by its structure of alternating sections that provide contrast while incorporating a recurring theme, typically labeled as section A. In a Rondo, the main theme (A) reappears after contrasting segments (B, C, etc.), creating a lively and engaging musical experience. This recurring nature allows the listener to enjoy familiar material interspersed with different musical ideas, which is a hallmark of the form.

Other forms mentioned, such as Minuet and Trio, also feature contrasting sections, but it is more about the specific dance structure than the broader alternating pattern that characterizes a Rondo. Cyclic form refers to the use of thematic material across multiple movements, rather than focusing solely on a single recurring section amidst contrasts. Passacaglia involves variations over a repeated bass line or harmonic progression, which notably does not align with the concept of alternating contrasting sections in the same way as the Rondo does. Thus, Rondo form is distinctly defined by that balance of repetition and contrast.
