The right answer is D

Among all the vital functions, two of them are particularly important, because they concern the very existence of life within the biosphere:

*one is the  photosynthesis, which is nothing less than the source of all energy and matter  organic,

*the other is the breath, purveyor of the energy necessary for the functioning of the vast majority of living beings.

the correct answer is b

when you breathe in, or inhale, your diaphragm contracts (tightens) and moves downward. this increases the space in your chest cavity, into which your lungs expand. the intercostal muscles between your ribs also enlarge the chest cavity. they contract to pull your rib cage both upward and outward when you inhale.
