I can help you! What is your question?
I think your answer is D. However I’m not 100% sure.
The rock cycle is referred to as cycle because it repeats over and over again. The definition of cycle is a series of events that are regularly related in the same order. So with the rock cycle they stay in the same order and repeat.
Hope this helps :)
Shale actually forms in the part of the rock cycle called compaction.
