01 What is the simple meaning of proportion in art?
Answer and explanation
Correct answer: A. Relationship between the sizes of parts
Explanation: The governing concept is proportion, which compares the sizes of parts within an object or composition. Option A is correct because proportion asks whether those parts relate appropriately to one another and to the whole. Mixing colours concerns colour practice, line direction concerns the element of line, and an empty area concerns space. Thus proportion is specifically a relationship of size, not colour, direction, or emptiness.
