How Many Examples Are Enough for an Illustrating Paragraph

How many examples are enough for an illustrating paragraph?

A) Since two or three short examples are sufficient, you don't want to depend on just one long extended example because there isn't enough meat to it.
B) The number depends on the point you are trying to make.
C) If your point is very complex, you want to count on using three to four examples, but if your point is simple, two examples are more than enough.
D) You want to include as many examples as possible to make sure you make your point.
