Answer:
Form
Step-by-step explanation:
quote to back me up:
"Form is actual, three-dimensional shape, though it is often used to describe the illusion of three-dimensionality, as well. Like shape, form can be geometric or organic."
Form would be the form of an object and that usually if not always involves 2D and 3D.
I do not know why the others are saying texture because texture is related to how something looks like it feels. (like if you drew a lot of hair to make something feel fluffy, the texture would be fluffy or hairy)
