This excerpt features what instrumentation?

The correct answer highlights a piece that showcases the interaction between a piano and an orchestra, illustrating a dialogue between the two. This alternation creates a dynamic texture where the piano stands out against the larger orchestral backdrop, allowing for a rich and varied musical experience.

In such a composition, you might expect to hear sections where the orchestra provides the foundational harmonies and thematic material, while the piano interjects with virtuosic passages, embellishments, or soloistic statements. This interplay is characteristic of works where the piano and orchestra function together, each bringing their unique qualities to the performance.

Other options do not capture the essence of this specific excerpt. For instance, a solo piano only would imply a lack of orchestral context, making the texture less rich than what is described. Similarly, strings and woodwinds or a woodwind quartet would suggest a different ensemble setup that does not include the piano as a primary instrument engaged in alternation. Thus, the selection of piano and orchestra in alternation rightly represents the instrumentation depicted in the excerpt.
