Question

an element of art that is three - dimensional (3d) and encloses volume
sphere cube cylinder cone pyramid
○ form
○ texture
○ line
○ value

Explanation:

To solve this, we analyze the definitions of each art element:

• Form: Defined as a three - dimensional (3D) element that encloses volume. The examples (sphere, cube, etc.) are 3D and enclose volume.
• Texture: Relates to the surface quality (smooth, rough, etc.) of an object, not about being 3D and enclosing volume.
• Line: A one - dimensional element (has length, no width or depth in basic terms), so it's not 3D.
• Value: Refers to the lightness or darkness of a color, not related to 3D or volume.

So the correct option is the one with "Form".

Answer:

A. Form (assuming the first option is "Form", as per the options given: Form, Texture, Line, Value)
