Hint: Phenol is an aromatic organic compound. If you remember the structure of phenol, you can see that a hydroxyl group i.e. -OH is attached to benzene.. Bakelite is a thermosetting polymer used in electrical systems. All the organic compounds are used in wide number of ways like in industries,pharmaceuticals,petrochemicals etc

Complete answer:
In order to answer this question, we need to know the composition and preparation of the above mentioned substances. Bakelite is widely used in industries, it is prepared by combining phenol with formaldehyde through polymerization reaction. Polystyrene by the name is prepared by combining many units of styrene. Styrene is known for its polymerization reaction. Now,coming to Nylon which is made by a polymerization reaction between a carboxylic acid and amide. In PVC, many monomers called vinyl chloride combine together forming PVC. So, phenol was used as one of the constituents in preparation of Bakelite.

So, the correct option is A.

Bakelite is considered as the oldest plastic which is synthesized by humans. Phenol is taken into the reaction mixture and when formaldehyde is added in a quantity more than the phenol ,a product known as Resol is formed due to condensation. Now, novolac is allowed for cross linking in the presence of phenol. As a result,bakelite is formed.
