Carbon dioxide releases from the body by the lungs.

Option: C

Step-by-step explanation:

Lungs are the respiratory organs of the body. They help in the gaseous exchange of "carbon dioxide" to the atmospheric oxygen. The carbon dioxide released from the tissue as an end product of the "citric acid cycle" and dissolves in the blood in the form of bicarbonate Ion or simply bind with hemoglobin molecule of the RBC. During circulation when the blood is pumped into the lungs then the carbon dioxide is released from the lungs and oxygen is inhaled.
