Answer:
D.
Step-by-step explanation:
So, you know that a quadrilateral is a 4 -sided shape, which is what the polygon is. If 4 more sides are added, you already know that b. can be eliminated.
decagon's are shapes with 10 sides I believe, where you are looking of row with 8. So, this is not it. Eliminate A.
A pentagon is a 5- sided shape. So, you know that is an immediate elimination as well.
That leaves you with d. octagon:
As an octopus has eight legs, just as an octagon has 8 sides.
