All the options can serve as a CS. The passage of time (A) can be a CS for classical conditioning (e.g. salivating at a specific time of day when regularly fed at that time), a tone (B) can also serve as a CS (e.g. a dog salivating at the sound of a bell that has been paired with food), and one's external environment (C) can be a CS in various classical conditioning situations (e.g. a child developing a fear of dogs after being bitten by one). Therefore, D is the correct answer.
