1 Pyretics
2 Antipyretics
3 Antibiotics
4 Antiseptics
Explanation:
An Antipyretics is a type of medication that prevents or reduces fever by lowering body temperature from a raised state.

Cresol is
1 A mixture of three cresols with little phenol
2 Used as dye for wood
3 A soapy solution of cresols
4 Having an aldehyde group
Explanation:
It’s Obvious.

Phenol is used in the manufacture of
1 Bakelite
2 Polystyrene
3 Nylon
4 \(PVC\)
Explanation:
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.
