B Correct answer
Explanation

Polythene (polyethylene) is formed by the polymerization of ethene (ethylene) monomers. When ethene molecules undergo addition polymerization, they link together to form the long chains that make up polythene. Propene would give polypropylene, ethyne is a different alkyne, and ethane is a saturated hydrocarbon.
