The correct answer is carbon dioxide.
Lungs expel waste from the body in the form of carbon dioxide. When we breathe in, oxygen enters our lungs and is transferred to our blood, which then carries it to our body's cells. During this process, our cells produce waste in the form of carbon dioxide. The carbon dioxide is then transported in the blood back to the lungs, where it is exhaled out of our body when we breathe out. So, the lungs play a crucial role in removing carbon dioxide waste from our body.
