Choose the correct answer:
 
The given diagram shows a ray of light passing from Medium A into Medium B. The angle of incidence is \(60^{\circ}\) and the angle inside Medium B is \(45^{\circ}\). Answer the following questions considering the system as a rectangular glass slab.
 
Given that the angle of incidence is \(60^{\circ}\) and the angle of refraction is \(45^{\circ}\), what will be the angle of emergence?
