A symphony is a sonata for orchestra. The correct answer would be option C.
A symphony is a lengthy piece of Western classical music, most frequently written for orchestra. Although the term's origins date back to the ancient Greek era, it has been used to refer to a variety of things. However, by the late 18th century, it had acquired the meaning that is now widely accepted: a work that typically consists of multiple distinct sections or movements, frequently four, with the first motion in sonata form. The orchestra for a symphony is typically composed of a string section, brass and percussion instruments, totaling between 30 and 100 performers. In a musical score that includes all the instrument parts, symphonies are notated. Orchestral players use parts that only have the transcribed music for their own instrument. Vocal sections can also be found in some symphonies.
