Explanation:

A circle is defined as the set of all points in a plane that are equidistant from a fixed - point (the center). Option A is incorrect as a circle is not similar to a hexagon. Option B describes a pair of parallel lines equidistant from a given line. Option C is incorrect because a polygon has straight - sides, and a circle is not a polygon. Option D correctly states the definition of a circle.

Answer:

D. The collection of all points in a plane that are the same distance from a given point
