Answer:
The correct answer is letter B. internal.
Step-by-step explanation:
The internal mode of acting - also known as method acting - asks the actor to find a psychological identification with the character. The actor tries to build the character from within, by becoming intimate with the character's life and intuition. The mind of the character is thus developed. It's as if the actor believes himself to be the character and asks himself what he would do if he were in that situation. If the feeling comes, the action will follow. If the actor can feel, the character will act.
