The correct option is B
P-2; Q-4; R-1; S-3

The carboxylic acid group has general structure formula $R - O | | C - O - H$ .
An alkyne is one where there is a triple covalent bond between two carbon atoms.
An ester is an organic compound with general structure formula $R - O | | C - O - R^{'}$ .
A ketone is an organic compound with structural formula $R - O | | C - R^{'}$ .
Here, R = alkyl group.
