Answer to Question 1

C

Answer to Question 2

Reducing confining pressure lowers a rock's melting temperature. When confining pressure drops sufficiently, decompression melting is triggered. Decompression melting occurs where hot, solid mantle rock ascends in zones of convective upwelling, thereby moving into regions of lower pressure.
