C organs because molecules combine to form cells and organs combine to make organ systems
The correct option is D.
Noble gases are very stable, because they have eight electrons in their outermost shells. This is called octet form. Other elements that do not have the octet form try to achieve the form by forming bonds with other elements. Because of their stability, noble gas are chemically inert, that is, they do not undergo chemical reactions with other elements.
They do not have lungs. They have gills tat help them get the oxygen out of the water around them.

Answer:
Bad form.
Explanation:
Bad form of ozone causes breathing difficulty due to its availability near the surface of earth and its composition. Ozone is not emitted directly into the air, it is created due to the chemical reactions between oxides of nitrogen and volatile organic compounds. When these pollutants react with each other in the presence of sunlight, ozone is produced which leads to difficulty of breathing as well as damages the vegetation so this ozone is considered as bad ozone.
