The answer is c. Ozone.

Here's why:

a. CO2 (Carbon Dioxide) - This is a primary byproduct of burning coal. When coal is burned, the carbon in coal combines with oxygen in the air to form carbon dioxide.

b. NOx (Nitrogen Oxides) - These are also produced when coal is burned. Nitrogen in the air reacts with oxygen under high temperature and pressure conditions in the boiler to form nitrogen oxides.

c. Ozone - This is NOT produced by burning coal. Ozone is a gas that occurs both in the Earth's upper atmosphere and at ground level. It can be good or bad, depending on where it is. Ozone at ground level is a harmful air pollutant because of its effects on people and the environment, and it is the main ingredient in “smog."

d. SO2 (Sulfur Dioxide) - This is another primary byproduct of burning coal. The sulfur in coal reacts with oxygen to form sulfur dioxide, which can be a major source of air pollution if not properly controlled.
