Quizplus · Accepted Answer

The crust containing igneous activity, deformation, and metamorphism can provide evidence of past mountain ranges. These features occur due to the tectonic forces involved in the formation and destruction of mountain ranges.

Answer: C 
 Fossils of mountain-dwelling plants and animals can also provide evidence of the past existence of a mountain range. These fossils may be found in sedimentary rocks that were deposited in mountain environments, such as near rivers or in shallow seas.

Therefore, the best choices are B and C.
