The Correct Option is A
Solution and Explanation
Novolac is a phenol-formaldehyde polymer. The monomer ‘x’ is phenol, which reacts with formaldehyde in the presence of a base (OH–) to form Novolac through condensation polymerisation. The correct structure for phenol with a hydroxymethyl (-CH2OH) group is shown in option (1).
