Concept:A soliloquy is a dramatic device in which a character, while alone on stage, speaks his or her innermost thoughts aloud.
Explanation:The question asks for the technical term that fits this exact stage situation.
Option A, a monologue, is a lengthy speech directed at other characters or the audience, not necessarily given when the speaker is alone.
Option B, an aside, is a brief private comment meant for the audience only, while other characters on stage remain unaware of it.
Option C, an epilogue, refers to a closing speech delivered after the main action of the play has come to an end.
A soliloquy, however, requires that the character be completely alone, voicing his or her private thoughts to no other person on the stage.
Since the speech in the question is one in which a character speaks his or her thoughts while alone, it matches the definition of a soliloquy exactly.
Thus, the correct choice among the given options is option D.
Answer:D. a soliloquy
