b. soil
c. bodies of water
d. all of the above
Phosphorus is contained in living organisms, soil, and bodies of water. Thus, the correct answer for this question is D, i.e. all of the above.
The functions of Phosphorus are as follows:
Phosphorus is contained in the genetic material of living organisms. It is also present in the soil which is one of the essential primary macronutrients along with nitrogen and potassium. Phosphorus is also present in water bodies.
Therefore, phosphorus is contained in living organisms, soil, and bodies of water. Thus, the correct answer for this question is D, i.e. all of the above.

Explanation:
During inflation, air moves in the lungs when the air pressure within the alveolar spaces falls below the atmospheric pressure
The forces that normally cause changes in volume of the chest and lungs arises not only from muscle contraction but from the elastic properties of both the lung and the chest
The force required to maintain inflation of the lung and to cause airflow is provided by the chest and diaphragm (the muscular partition between chest and abdomen), which are in turn stretched inward by the pull of the lungs
Hence during lung inflation, the lungs cling to the internal surface of the chest wall as it expands
