Option B.

Explanation:

Any object that was made or modified by humans, is the right answer.

An artifact is anything produced or given contour by humans, such as a weapon or an artwork, particularly an object of archaeological importance.

In the context of archaeology, however, the term has displayed a course of special distinction and is described as something obtained by archaeological effort, which can be a cultural artifact having an aesthetic concern.
