Which of the following raw materials is used in a plastic industry?

Ethene is the raw material used in the plastic industry. Ethene is a colorless gas with a sweet smell and is a type of hydrocarbon that is produced from crude oil and natural gas. It is used as a feedstock in the production of many chemicals, including polyethylene, which is the most widely used plastic in the world. The polymerization of ethene produces polyethylene, which can be molded into various shapes and forms to produce plastic products. Methane is also a hydrocarbon, but it is not commonly used as a raw material in the plastic industry. Calcium and hydrogen are not hydrocarbons and are not used as raw materials in plastic production.
