An organic compound (A) of the molecular formula ${\mathrm{C}}_6{\mathrm{H}}_{12}{\mathrm{O}}_3$ gives a positive Iodoform test but does not reduce Tollen's reagent. When (A) is subjected to acid-catalyzed hydrolysis, another compound B is formed which gives positive Tollen's test. Identify the unknown compound (A).

The ${\mathrm{pK}}_{\mathrm{a}}$ values of some of the acids are given below:

Acid	\(\mathrm{pK_a}\)	Acid	\(\mathrm{pK_a}\)
	-0.6	HI	-10.0
	4.8	\(\mathrm{HC} \equiv \mathrm{CH}\)	25
\(\overset{+}{N}H_4\)	9.4	\(H_2S\)	7.0

The correct order of leaving tendency of their conjugate bases is:

1.
2.
3.
4.
