In your laboratory you trace the path of light rays through a glass slab for different values of angle of incidence (Zi) and in each case measure the values of the corresponding angle of refraction (Zr) and angle of emergence (Ze). On the basis of your observation your correct conclusion is:

When a ray of light passes through the glass slab, then the angle of incident is found to be nearly equal to angle of emergence and greater than angle of refraction.
