The answer is all of the above except choice 3.
In a business setting, you never want to use a detached tone. This gives the impression to your colleague/boss/etc. that you don't care and don't really want to be there. It shows that you don't see them as important and don't care about what they have to say. It won't achieve anything for you.
<span>While I was changing my shirt, I d**n near gave my kid sister Phoebe a buzz, though. I certainly felt like talking to her on the phone. Somebody with sense and all. But I couldn't take a chance on giving her a buzz, because she was only a little kid and she wouldn't have been up, let alone anywhere near the phone. I thought of maybe hanging up if my parents answered, but that wouldn't've worked, either. They'd know it was me. My mother always knows it's me. She's psychic. But I certainly wouldn't have minded shooting the cr*p with old Phoebe for a while.</span>
