• B. industrial processes
• C. stationary fuel combustion
• D. volcanoes

Answer 1

The correct option is B

industrial processes

Explanation for correct option

(B) Industrial Processes

Principal source of volatile organics (hydrocarbons)

• The name 'hydrocarbon' is self-explanatory, referring to the compounds of hydrogen and carbon.
• Large industries like chemical producers and combustion sources like fossil fuel-burning power plants are sources of VOC.

Explanation for incorrect option

• In transportation fuel (hydrocarbons) are burnt and sulfur dioxide, carbon dioxide, and other gases are produced.
• Solid, liquid, or gaseous fuels are burned to produce energy in stationary fuel combustion.
• Volcanoes produce sulfur dioxide, ash, and dust.
• Hence, options (A), (C), and (D) are incorrect.

Hence, option (B) is correct. The principal source of volatile organics (hydrocarbons) is industrial processes.
