Answer:
<h2>Hexagon.</h2>
Step-by-step explanation:
To solve this problem we don't need to graph it.
If you think this through, you will find that each pair of two points represents one side of the polygon.
So, based on the given information, the sides of the polygon are:
MN, NO, OP, PQ, QR and RM.
As you can observe, there are 6 sides in total. So, a polygon with six sides is called Hexagon.
Therefore, the right answer is the second choice.
