doctors (they is the pronoun that replaces doctors)
A is the answer.
The pronoun is: theyThe antecedent is: patients
The sentence is grammatically poor, so I will have to take an educated guess at the correct form.They is the plural pronoun in the sentence, there are two possible antecedents, doctors and patient. Doctors is plural and therefore the logical choice, but they wouldn't be spending much time in the waiting room - that's for patients. I must therefore assume that patient is a typo and should really be patients, therefore the antecedent is patients
The compound noun in the sentence "The doctor's waiting room is always crowded with patients" is "waiting room." It combines the two words "waiting" and "room" to refer to a specific type of room designated for patients to wait in.
waiting and costomer in doctor
The doctor has four patients waiting to see her.
i think it's meant to relax the patients (but personally i hate the look of fish and to me it's like putting a tank of spiders in the room!)
Doctors
No, it is not an adverb. Waiting is a verb form and gerund (noun), and can be an adjunct or adjective (waiting patients, waiting room). The seldom used adverb form is waitingly.
