The correct answer is (D) A man-made object, particularly a primitive tool, vessel, or weapon; any object made with skill by man, especially one intended for reuse. A simple, man-made object, that gives evidence of an ancient culture.

Artifact comes from Latin arte+ factum (object made with skill).

Examples of use:

• One of the artifacts was probably a fragment of a clay pot.
• The site of the dig yielded a great number of artifacts.
