Assertion (a): High-temperature, low-pressure metamorphism occurs on the over-riding plate near convergent plate margins

Q. Assertion (a): High-temperature, low-pressure metamorphism occurs on the over-riding plate near convergent plate margins.

Reason (r): Partial melting in the mantle wedge generates magmas that rise to form the arc.

A. (a) is true but (r) is false.

B. (a) is false but (r) is true.

C. Both (a) and (r) are true and (r) is the correct reason for (a).

D. Both (a) and (r) are true and (r) is not the correct reason for (a).

Ans: Both (a) and (r) are true and (r) is the correct reason for (a).
