Question

What should you do when asked to take down a detailed message for your manager or supervisor? A. Politely suggest that the caller call back when you know your manager will be in the office to receive the call directly. B. Repeat the message back word for word after it's been given. C. Politely suggest that the caller leave a voicemail message instead. D. Make your best guess when you don't understand a detail rather than indicate your uncertainty.

Answer 1

The answer is B. Repeat the message back word for word after it's been given. 
Your manager or supervisor might be busy, so it would be best if you record the message on your own so they could read it.
When doing so, you need to repeat the message back word for word, because the messenger will be most likely to notify you when you get something wrong. This will ensure that you wouldn't misinterpret the message  given for your manager/supervisor

Answer 2
