This is such a question which can't be finished within 30 mins. I can't notice the angles. Friends, let's check them again. If you can't notice, try again. Also let's practice these types of questions. This will help you to sharpen these skills. By practising, you all can have the ability to do these questions within just a few secs. I'm trying to solve this problem.

The correct answer is C 7, We have different angles: Acute angle, Right Angle, Obtuse angle, Straight Angle and last which we all missed is REFLEX ANGLE. Please look at the ray inside i.e., corners inside which makes 7 reflex angles !! Kudos!! Happy Studying
