Explanation:

A bisector is defined as a line or line - segment that divides a geometric entity (like an angle or a line - segment) into two equal parts. Option A describes a compass, option B just mentions a perpendicular line which is not the definition of a bisector, and option D describes an arc related to constructing an equilateral triangle, not a bisector.
