Debussy's Prelude to the Afternoon of a Faun is often described as

1 point
Sacred Music (for the church)
A battle between hero and fate
A half-man/half-goat waking up in the morning
Chance Music

A half-man/half-goat waking up in the morning.

is this right?

No, that is not correct. Debussy's Prelude to the Afternoon of a Faun is not about a half-man/half-goat waking up in the morning. It is actually a symphonic poem inspired by Stéphane Mallarmé's poem "Afternoon of a Faun" and depicts the dreamy and sensual awakening of a faun in a mythical forest.
