B. Stress caused by forces that stretch an area of the crust made the rock to break
Explanation:
From the picture inserted to this problem, we see a unit that has been severely fractured. 
Fracturing results from the brittle deformation of a rock under applied stress. 
- Rock fracturing results in the formation of joints and faults. 
- We can obviously see different sets of joint sets on the body of the rock in the picture attacked. 
- Also, a prominent fault which resembles an extensional fault can also be seen. 
- Therefore, the stress caused the stretch of the area which in turn makes the rock the rock to break.

Animals eat plants and pass the phosphorus through the food chain from one animal to the other.
An animal dies and decomposes, returning the phosphorus to the soil.
