In a speech on the characteristics of a diamond, Kelley used an easel and a series of large photographs attached to a foam board to illustrate her points. When she began her speech, she had the top picture turned over, so the audience could not see it. As she discussed each characteristic, she uncovered the photograph appropriate to it. Which guideline for using visual aids was Kelley using

This question is missing the options. I have found the complete question online, and the answer options are the following:

Which guideline for using visual aids was Kelley using?

A. use technology thoughtfully

B. keep your visual aids simple and to the point

C. time your visuals to coincide with your discussion of them

D. polish your visual aids

The guideline Kelley is using is:

C. time your visuals to coincide with your discussion of them

Explanation:

According to the passage, Kelley only reveals parts of the photograph at specific times to help illustrate what she is talking about. She is timing her visuals, only showing something when it will cause more impact and support her point. This is an effective way to keep your audience interested. People will remain curious about the covered parts of the picture and how those parts will be connected to your speech.
