Arrange the products I, II, III from the following reactions in decreasing order of their acid strength.

Consider the following reactions

$Y$ can not be obtained from which of the following reaction?
Assertion (A) : Carboxylic acids are more acidic than phenols
Reason (R) : Resonance structures of carboxylate ion are equivalent, while resonance structures of phenoxide ion are not equivalent.
In the reaction sequence $Y$ is
