Final answer:
The most suitable way to answer an incoming call at a doctor's office is to say, "Dr Brown's office, Melinda speaking," as it is professional and provides necessary information to the caller.
Step-by-step explanation:
The most appropriate initial response to an incoming telephone call in a professional setting, like a doctor's office, is C. "Dr Brown's office, Melinda speaking." This response promptly identifies the workplace and the person answering the call, which is key to establishing a professional tone and clear communication. Compare this to a simple greeting or providing only the telephone number, which lacks the context that can assist callers in knowing they have reached the right place.
Moreover, option C is polite and welcoming, setting a positive tone for the call. It also opens the door for the caller to continue the conversation, whether they need further assistance or wish to speak to someone specifically.
