    D Carbon monoxide Correct Answer Incorrect Answer

    Solution

    Ethylene (C₂H₄) is used in the manufacturing of polythene (polyethylene). Polythene is produced through addition polymerization of ethylene, which is primarily obtained by cracking ethane and propane, as well as other materials like naphtha and gas oil.
