Rondo forms in the classical period are most often found in option (d) i.e, final movements.
A rondo is an instrumental form in music that consists of the initial articulation and subsequent restatement of a particular subject or piece, separated by opposing material.
A sonata, concerto, symphony, or another multi-movement piece typically ends with a rondo as the final movement. Although the structure of a rondo is quite simple, the variations that composers choose to employ that form in are frequently complex. A melody is repeated in each rondo, with contrasting musical passages in between.
The two most common forms of a rondo are the 5-part version and the 7-part form. The 5-part form generally uses the pattern ABACA, but the 7-part form typically uses the pattern ABACABA.
