Terylene (Dacron) is made by polymerising

Ahexamethylenediamine and terephthalic acid
Bethylene glycol and terephthalic acid
Cethylene glycol and phthalic acid
Dethylene glycol and adipic acid

Answer: B

Terylene is the polyester of ethylene glycol (ethane-1,2-diol) with terephthalic acid (benzene-1,4-dicarboxylic acid). The glycol with phthalic acid gives glyptal.
