Which of the following is a synthetic source of plastic?

Explanation:
Plastics are made by linking small molecules (monomers) into long chains (polymers) through chemical reactions. The most common way to get those monomers is from petrochemical feedstocks derived from crude oil. Refineries process crude oil into building blocks like ethylene and propylene, which are then polymerized into widely used plastics such as polyethylene and polypropylene. Water doesn’t provide monomers for plastics, and while wood and soil are natural materials, they don’t serve as the typical source of the synthetic monomers used in standard plastic production. Therefore, crude oil is the synthetic source of plastic.
