Answer:
A. It creates dramatic tension.
Step-by-step explanation:
The words spoken by the character and the internal thoughts of the character creates dramatic tension in the narrative. Soliloquy is the literary device in which the character's thoughts are disclosed only in front of the audience. It creates a situation in which the audience is aware of the real situation and thought of the characters. By hiding the real thoughts, the character builds a veil in front of the eyes of the person he is speaking to.
