C.

D. The circulatory system transports oxygen that the respiratory system brings into the body.

Explanation:

the first two answers either refer to carbon dioxide as beneficial and necessary to the body(it sometimes is but not in this case)

the answer choice c refers to oxygen being transferred directly to the heart. This is also incorrect.

the only proper answer to this question is answer choice d.

answer: the metamorphic rocks are formed when they are exposed to high pressure and high temperatures. this happens when one of the earth's plates comes in contact with the other plate by traveling in opposite directions, straight into each other or slipping under one another. the friction that is caused by this activity results in   melting of rocks and when it cools they are known as metamorphic rocks. this process needs a controlled amount of pressure and temperature otherwise it may turn into magma.
