1. Given
2.Both Angles Are in straight line.
3.definition of supplementary Angle
4.substitution
5.opposite angles are equal (vertically angles)
6.from statements 4 and 5.
7.from statements 6.

In the first triangle 80+20+p=180 (since sum of all angles of a triangle is 180)so p= 80also in second triangle 55+45+q=180 (since sum of all angles of a triangle is 180)so q=80so we can conclude that p=80 degrees q=80 degrees so p=q=80 degreeshence option b is correct
