A circle is simply a curve made up of all the points that are the same distance from the center. This distance is called the radius of the circle. It's important to know that <em>all circles are similar to each other</em>, but what is similarity? It's simply, shapes are similar if we can turn one into the other by moving, rotating, flipping, or scaling. So every circle can match any other circle by moving it, rotating it, flipping it, or scaling it.
Then circles O and Q shown below are similar no matter what's the radii of them.

Answer: OPTION B.
Step-by-step explanation:
The equation of a line that passes through the origin has this form:
Where "m" is the slope of the line.
By, definition, Proportional relationships have the following form:
Where "k" is the Constant of proportionality.
Therefore, the graph of a Proportional relationship is a straight line that passes through the origin. Then:
As you can observe in the picture attached, if you connect the ordered pairs shown in the graph, you get a line that does not pass through the origin.
Therefore, you can conclude that the relationship between those two quantities is not proportional.
