Answer:
D. Bell Curve
Explanation:
Think about it like a test on a quiz. Let's say for the sake of the students, that most of the pupils got a score of 80. On the distribution, this would be the high point. Of course, less people got a 50 or 100, so these would be low points. This would create a kind of hill, or slope, which comes back down. This is also called a bell curve in many cases.
