उत्तर
Both A and R are true and R is the correct reason for A.
Explanation:
Waves slow down near the shore because the water depth decreases and the wave base starts to touch the sea floor. The friction between the sea floor and the wave reduces its speed and causes it to slow down as it approaches the shore.
