What is the strongest basis for distinguishing public art from private artwork?

Location, audience group, and social dialogue

The governing concept is that public and private art are distinguished mainly by social setting, access, and intended relationship with viewers, not by a particular colour or size. Public art is usually placed in a shared or accessible environment and addresses a broad, changing audience; it may invite discussion about memory, identity, history, or community concerns. Private artwork may be made for personal use, a restricted collection, or an individual experience. Therefore, option C is correct because location, audience, and social dialogue work together. Option A and option B are merely formal features that can occur in either setting, while option D describes motivation rather than the artwork's public status.
