Answer:
A.
Step-by-step explanation:
I- I don't really have an explanation, but A sounds best because comparisons makes things a lot more easier to understand, its kinda like giving an example to a math problem
It's not B because the listeners would be confused
And its not C because if its too general, they might move away from the topic you're explaining?
Sorry if you get this wrong, I really tried my best :')
