Answer:
Option D.
Step-by-step explanation:
The given vertices of a polygon are D(-4,5),E(-1,5),F(1,2), and G(-1,-1).
Here, number of vertices is 4.
In heptagon, number of vertices = 7
In hexagon, number of vertices = 6
In octagon, number of vertices = 8
In quadrilateral, number of vertices = 4
Since the given polygon has 4 vertices, therefore it is a quadrilateral.
Hence, option D is correct.
