The air we breathe in contains about 0-04- of carbon dioxide-The air we breathe out contains about 4- of carbon dioxide-In other words- exhaled air contains 100 times the concentration of carbon dioxide than inhaled air-Hence the correct option is -c-

The air we breathe in contains about 0.04% of carbon dioxide.The air we breathe out contains about 4% of carbon dioxide.In other words, exhaled air contains 100 times the concentration of carbon dioxide than inhaled air.Hence the correct option is {c}

The air we breathe in contains about $0.04 %$ of carbon dioxide.
The air we breathe out contains about $4 %$ of carbon dioxide.
In other words, exhaled air contains 100 times the concentration of carbon dioxide than inhaled air.
Hence the correct option is {c}
