You can best deal with visitors that drop into your office by a. telling them you are busy now and suggest an alternative time to talk. b. telling them you don't have time to talk to them. c. telling them to make an appointment with your assistant. d. always keeping your office door closed.

Hi!

That's a funny one xD

The correct answer is A
Tell them you are busy now and suggest an alternative time to talk.

The other options are not good because if you just tell them you are bus now, you will lost the client. They will think you are not care for them. You can't tell them to make an appointment with your assistant because they want to talk with you,not the assistance. OMG always keeping the door closed is the worst xD. It shows that you don't welcomed people so you wouldn't have enough client.

I hope this helps!

Theory W is the answer. Have a good day
