I believe the correct answer is B. They show that Olivier’s Hamlet is very thoughtful and analytical.
Sir Laurence Olivier's interpretation of Hamlet underlines the character's high intellectualism. He is really a person who thinks, above and before anything else, and regrets for not acting more (or faster). He is gloomy not because of his melancholic nature, but because he has found himself in a dire situation, and he has to be absolutely sure what is the right thing to do.
