As we know Reflex angle is the angle which is greater than 180° but less than 360°.
it is the largest angle between all angles.
The smallest angle is acute and largest is obtuse but the Reflex angle is Greater than obtuse but less than a angle made by circle.
In the figure shown two parallel lines are cut by a transversal.
Now if we take point M as the vertex it's reflex will include points QLR.
So among all the options option (A) is correct.
Other three options doesn't fulfill the criteria .
