Be sure the humor you use in your presentation is
a. funny
b. vivid
c. appropriate
d. attention getting

The correct answer is C) Appropriate. Hope this helps.

Hello! The word that fits in the best is appropriate, since the other words don't fit in as well. For example, attention getting is not a proper word. Also, vivid means to use detailed language to create an image in the listeners. Humor needs to be direct, so vivid not the right answer. Funny is too generic, and doesn't fit well as in "funny humor." The answer would be appropriate. Hope this helps! :)

Dwould be the answer
