In a polymer recycling plant, polymer “X” was depolymerized by glycolysis in the presence of ethylene glycol and a suitable catalyst. The glycolysis reaction yielded the following compound:
\[
\[\text{HO-CH}_2\text{CH}_2\text{-O-C(=O)-}\text{C}_6\text{H}_4\text{-C(=O)-O-CH}_2\text{CH}_2\text{-OH}\]
\]
Identify the polymer “X” from the following options.
