Terylene is manufactured from
Aethylene glycol and benzene-1,2-dicarboxylic acid (phthalic acid)
Bethylene glycol and benzene-1,4-dicarboxylic acid (terephthalic acid)
Chexane-1,6-diamine and benzene-1,4-dicarboxylic acid
Dpropane-1,2,3-triol and hexanedioic acid
Answer: B
Terylene (Dacron) is the polyester of ethane-1,2-diol and the para diacid, terephthalic acid (commercially via dimethyl terephthalate or bis(2-hydroxyethyl) terephthalate). The ortho acid or a diamine would give different polymers.
