How Does Refraction Affect the Shape of Incoming Waves Along

How does refraction affect the shape of incoming waves along a beach?

A) As the waves move into shallower water, the angle between the wave crests (troughs) and the shoreline decreases.
B) As the waves move into shallower water, the angle between the wave crests (troughs) and the shoreline increases.
C) As the waves move into shallower water, the wave slows down and the crests spread farther apart.
D) As the waves move into shallower water, the wave loses energy to the seabed, decreasing the wave height.
