That would be B.
The set of points are all on the line which is a bisector.
The correct answer is option B.
An angle bisector or the bisector of an angle is a line that divides an angle into two equal angles. If a point is marked on the bisector of an angle then that point will be equidistant from the sides of the angle.
Hence, option B - The set of all points in a plane that are equidistant from the two sides of a given angle.
