Most gaseous pollutants come from a group of chemicals called
a. oxides
b. chlorofluorocarbons
c. ozones
d. hydrocarbons

The correct answer is option A, that is, oxides.  

Air pollution refers to the kind of pollution that takes place because of the discharge of noxious gases, like carbon monoxide, sulfur dioxide, chemical vapors, and nitrogen oxides. These gases can get involved in further chemical reactions once they reach the atmosphere, forming acid rain and smog.  

Air pollution can exhibit various kinds of health associated influences, both long term, and short term.  

false because ozone (o3) depletion does not cause global warming, but both of these environmental problems have a common cause: human activities that release pollutants into the atmosphere altering it.

global warming is caused primarily by putting too much carbon dioxide into the atmosphere when coal, oil, and natural gas are burned to generate electricity or to run our cars.
