Step-by-step explanation:
Polygons are 2 dimensional shapes with straight edges (no curved edges). The shape needs to be closed up entirely to be a polygon. It cannot have any intersecting line segments
A can't be a polygon because the shape isn't closed up entirely
C can't be a polygon because it is a 3d shape
D can't be a polygon because it has curved edges.
H can't be a polygon because it isn't closed up (there are no line segments).
I can't be a polygon because polygons cannot have intersecting lines
J can't be a polygon because polygons cannot have intersecting lines
