Bisphenol A (BPA), a cause of concern, is a structural/key component in the manufacture of which of the following kinds of plastics?

A
Low-density polyethylene
B
Polycarbonate
Correct Answer
C
Polyethylene terephthalate
D
Polyvinyl chloride

Explanation

Bisphenol A (BPA) is a primary structural monomer used in the synthesis of polycarbonate plastics, which are widely used in consumer goods like reusable water bottles and food containers. While Polyethylene terephthalate (PET) is a common tempting option due to its use in plastic bottles, it is chemically distinct and does not utilize BPA in its manufacturing process. The core concept being tested is the chemical composition of common polymers and the identification of specific industrial chemicals that pose environmental and health concerns.
