What is the correct order of acidity of the protons marked $\mathrm{A}-\mathrm{D}$ in the given compounds ?

JEE Main 2023 (Online) 30th January Morning Shift Chemistry - Aldehydes, Ketones and Carboxylic Acids Question 66 English

A $\mathrm{H}_{\mathrm{D}}>\mathrm{H}_{\mathrm{C}}>\mathrm{H}_{\mathrm{B}}>\mathrm{H}_{\mathrm{A}}$
B $\mathrm{H}_{\mathrm{C}}>\mathrm{H}_{\mathrm{A}}>\mathrm{H}_{\mathrm{D}}>\mathrm{H}_{\mathrm{B}}$
C $\mathrm{H}_{\mathrm{C}}>\mathrm{H}_{\mathrm{D}}>\mathrm{H}_{\mathrm{B}}>\mathrm{H}_{\mathrm{A}}$
D $\mathrm{H}_{\mathrm{C}}>\mathrm{H}_{\mathrm{D}}>\mathrm{H}_{\mathrm{A}}>\mathrm{H}_{\mathrm{B}}$

Accepted Answer

Acidity of an acid depends upon the stability of it's conjugate base.

H_C > H_D > H_A > H_B

H_C is hydrogen of carboxylic acid.

H_D removal will lead to stable carbanion.
