Question : Which of the following is not a natural source of hydrocarbon?
Option 1: Natural gas
Option 2: Coal
Option 3: Petroleum
Option 4: Mica
Correct Answer: Mica
Solution : The correct option is Mica.
Mica is not a naturally occurring source of hydrocarbons. Mica is a mineral made up of silicate layers that do not include any hydrocarbons. Natural gas, coal, and petroleum, on the other hand, are all hydrocarbon-producing sources. Natural gas and petroleum are mostly constituted of hydrocarbons, whereas coal is a carbon-rich substance created over millions of years from the remnants of plant elements. Mica, being a mineral, lacks the hydrocarbon molecules found in the other substances given.
