Final answer:
The correct greeting option for a business phone call is (B) 'Good morning/afternoon/evening, [company name], this is [your name]. How may I help you?', which is polite and professional.
Step-by-step explanation:
A proper greeting when answering the phone, especially in a business context, would be option (B) Good morning/afternoon/evening, [company name], this is [your name]. How may I help you? This greeting is professional and provides important information, such as the time of day, the company you're calling, the name of the person you've reached, and an offer of assistance. Other options like (A) 'Hello?' may be too informal for a business setting, (C) 'What do you want?' is rather abrupt and impolite, and (D) 'I'm busy, call back later' is dismissive and unprofessional.
In professional communication, whether it's over the phone, in person, or via email, it's crucial to make a good first impression. An appropriate salutation, a clear statement of purpose, and a polite closing are all fundamental to effective business communication.
