which is true about font use in presentation slides

a. bright font colors should always be used

b. only one font size should be used

c. font size should be at least 24. point

d. font and background color should contrast.

Should be D

Explanation:

These answers aren't to my liking, however the other answers don't make sense. A isn't true. B isn't true because slides generally use large or bold fonts for key ideas, vocabulary or the overall main concept. The sub details would be in a smaller font. C is limiting your options and isn't true for all scenarios. D doesn't make sense because you wouldn't be able to read the information presented. Despite this, this answer may be trying to say that they shouldn't be in rainbow colors and need to look appropriate and mature. This one is a very odd question. D is the only logical answer I could conclude with if I am right about my second guess about what D could mean.  Forgive me if I am wrong.

yeah it is i have the dark knight
