Answer:
c. they form adjacent to an intruding pluton, which provides heat for metamorphism.
Explanation:
- In metamorphic rocks, the contact metamorphism produces the aureoles in the surrounding zones of the rocks that get altered.
- There varies in the thickness from the from centimeters to several kilometers like the large granitic intrusions and they typically consist of non foliated rocks formed due to the heat sources and intruding plutons.

The Mekong river is one of the primary landforms in the South-east Asian peninsula wherein it stretches 4,200 km from Southern Cambodia to the north of Myanmar. In addition, the river system has been the source of transportation as well as fisheries in settlements surrounding it. The country where the river is not its primary water system would be Vietnam.
At the point when the measure of the surface region with respect to volume builds, the rate of weathering increments. Weathering is the breakdown of rocks at the Earth's surface, by the activity of water, extremes of temperature, and natural action. It doesn't include the expulsion of shake material.
