Spatial Organization
Hope this helped ^^
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.
The best transition word for the sentence would have to be C. Furthermore.
A and B are transition words that would be changing to good news, and D is for telling examples.
I hope its right!
