C Correct answer
Explanation

Cross-linked polyethylene is a form of polyethylene with cross-links. It is formed into tubing and is used predominantly in hydronic radiant heating systems, domestic water piping and insulation for high tension (high voltage) electrical cables. It is also used for natural gas and offshore oil applications, chemical transportation, and transportation of sewage and slurries.
