Answer:
B. If you plan to adopt a kitten, please bring a pet carrier.
That is a metaphor, for it is a direct comparison to to unlike things (world as a stage, men and women as players), without using "like" or "as."
The answer is B, movie. "Action" is used as an adjective here, so it cannot be an object when there is no noun present. "Saw" is a verb. "I" is the subject, so the only remaining option is B, movie. The question to easily determine what the object is would be "What did you see?" And the answer would be "A movie".
