Answer:
C. Propene
Explination:
Propene is an unsaturated organic compound, also known as propylene and methyl ethylene. It is a colorless gas with a faint smell of petroleum.
Propene is a by-product of oil refining and production of natural gas. As a result of cracking larger hydrocarbons, ethylene, propene and other compounds are formed during oil refining. A major source of propene is naphtha cracking intended to produce ethylene, but it also results from refinery cracking producing other products.
