The following are all components of what?

• positioning of actors on stage

• scenic backgrounds

• props and costumes

• lighting and sound effects

A. Staging

B. dialogue

C. Stage directions

D. Aristotle's Elements of drama

They answer cannot be D, because the positioning of actors on the stage isn't one of Aristole's elements of drama.

It cannot be C, because costumes aren't a part of stage directions.
