What part of an opera is the main melodic feature solo? a: overture b: ensemble c: duet d: prelude e: aria

The answer would be (E) aria.

Aria is a type of song in an opera where a singer, usually the main character, would sing a song alone.

Overture is incorrect because it is a song that is sung in the beginning of the opera, usually by more than one character. An ensemble is a song piece that is sung by multiple individuals, while a duet is sung by two people. A prelude is sung during the transitions between scenes, making it also incorrect.
