B. 1, 2, 4

• Nitrogen dioxide (NO2) is a reddish-brown gas that is soluble in water, and a strong oxidant.

• Ambient sources of NO2 results from high temperature combustion of fuels in processes such as those used for heating, transportation, industry and power generation.

• Household sources of nitrogen oxides (NOx) include equipment that burn fuels such as furnaces, fireplaces and gas stoves and ovens.

• Exposure to nitrogen dioxide can irritate airways and aggravate respiratory diseases.
