Final answer:
The combination of instruments in a piano trio is piano, violin, and cello, as this is the standard grouping for such an ensemble in chamber music, thus correct answer is 2) Piano, Violin, Cello.
Explanation:
A piano trio is a group of three musical instruments played together in a chamber music setting. The piano trio typically consists of a piano, a violin, and a cello, making it the most prevalent instrumentation combination. This ensemble should not be confused with other types of trios or bigger orchestral groupings, where various other instruments like the trumpet or the flute may participate.
The violin plays in a high range and often carries the melody within an ensemble, while the cello provides a rich, lower-pitched supporting harmony. The piano's role is both harmonic and melodic, and due to its wide range and the ability to produce multiple tones simultaneously, it serves as a foundation for the trio's overall sound.
