Answer
Both A and R are true and R is the correct explanation of A.
Explanation — A major volcanic belt is found along the Mid-Oceanic Ridge in the Atlantic Ocean. This is because volcanic eruption is closely related to sea floor spreading, where molten magma rises from beneath the Earth's crust, forming new ocean floor. This rising magma causes frequent volcanic activity along the ridge.
