Answer:
Protein
Explanation:
Protein is used to make insulation (like fat) and is used to store energy taken form food (please tell me if this works)
Option C
Plants, cellular respiration accurately represents a carbon source and the process that releases carbon from that source
<u>Explanation:</u>
Every existing body supplies CO2 off while they evoke power from their food through cellular respiration. Plants and creatures present off CO2 while living and respiring and during lifeless and rotting. Plants are significant carbon sinks, gaining up enormous volumes of CO2 through the manner of photosynthesis.
While plants also discharge CO2 during the means of respiration, the volume of CO2 exercised up by plants by photosynthesis and discharged by exhalation approximately matches out. Volcanic action, forest wildfires, and diverse anthropological exercises deliver carbon.
The percent yield is 74.4 %.

It is B, smoke and air pollution can stress the lungs and cause things like Respiratory distress if not wearing a proper mask. That is why in places with massive amounts of air pollution many people will wear face masks.
