Answer 1

Answer: The answer is C:

a region of compressed rock located behind a volcanic arc at a convergent continental margin.

explanation:

Typically found in orogenic forelands or in rear-arc position (e.g. on east side of Andes). It's formed during continent-continent collision, and often in passive margin sediments of the subducting plate (and hence can exhume the earlier rift margin that formed the foundation for the passive margin.
