What is the reason for Statement 2 of the two-column proof?a) Linear Pair Postulateb) Definition of anglec) Definition of bisectd) Angle Addition Postulate

The reason for statement 2 is: Angle Bisector Postulate. By definition, an angle bisector is a ray that is drawn at the center of the angle. When an angle bisector is drawn, it divides the angle into two equal parts. So, the individual angles ∠RPQ and ∠QPS must be equal.
