Maggie is preparing a business report. which types of keys will she use to type out words and numbers?

It is called "choke.

Ibelieve the answer is: b.  use a different transition for every slide to keep the audience's attentiona. that would make it boringc. sound effects might be distracting and some people might find it annoyingi hope that : ) 

Iwould recommend rereading her speech over and over with intensity until she feels comfortable with it.
