Focusing on feedback (such as the body language of the audience) is an example of an attempt to:
a. make preparational adaptations
b. acknowledge controversy
c. make presentational adaptations
d. analyze diversity

Focusing on the feedback of the audience can help to adjust the presentation to the specific needs of the audience.  (the correct answer is c. make presentational adaptations ). For example, if the audience seems bored you might want to make the presentation more interesting or if they seem confused, you might want to speak slower and focus more on the main points.
