A) Monologue: A long speech or performance by one actor, as if alone.

C) Soliloquy: A speech delivered by a character alone on stage, expressing their thoughts and emotions to themselves or the audience.
D) Dialect: A particular form of a language that is specific to a region or social group.

By considering these definitions, you can eliminate the options that don't match the given scenario. In this case, a monologue fits perfectly as the most appropriate term for an actor alone on the stage delivering a speech.
