Which polymer is used for the manufacturing of water pipes?

Correct option is D

The correct answer is: (D) PVC (Polyvinyl Chloride)

PVC (Polyvinyl Chloride) is the polymer commonly used for manufacturing water pipes. It is a durable, strong, and corrosion-resistant material, making it ideal for piping systems used in both cold and hot water distribution. PVC pipes are widely used due to their affordability and ease of installation.

•  Polystyrene: This is a brittle plastic used mainly for making containers, packaging, and insulation, not for water pipes.
