When you are choosing an image for a presentation, which of the following is the most important consideration? a. the image is colorful so it stands out. b. the image is relevant to the topic of the slide. c. the image was found in a google image search. d. the image distracts the audience from what the speaker is saying.

I would say the most important consideration is option choice B, its relevance. Looking at the other option choices we can easily rule them out:
A) often times bright images distract from the topic and speaker of the actual presentation
B) seems the most accurate, relevance to the topic is important
C) what does it matter if the image is from google image??
D) The image should NEVER distract from the speaker.

This leads me to believe B is the correct answer.

B. The image is relevant to the topic of the slide.
