C Correct answer
Explanation

Yes, it is correct. Polycarbonate has a glass transition temperature of about 147° C. Polysulphone describes a family of thermoplastic polymers. Its glass transition temperature is 185° C. Polydimethylsiloxane (PDMS) is a crystalline polymer with a glass transition temperature near -125° C. Polystyrene has a glass transition temperature of about 100° C.
