B) Petrouchka.
Petrouchka is one of Stravinsky's earliest works. The time period and style of these early works are referred to as Stravinsky's "Russian Period", before he began composing in the Classical Style, which is referred to as his Neoclassical Period. The Russian Period lasted from around 1907 - 1919, and Petrouchka was written in 1910. The Neoclassical period followed until 1954.
