An organic compound [A] having molecular formula $\text{C}_3\text{H}_6\text{O}$ gives a positive iodoform test. On reduction by $\text{LiAlH}_4$, compound [A] forms compound [B]. Further, compound [B] reacts with $\text{SOCl}_2$ and forms compound [C]. On treatment with alcoholic $\text{KOH}$, compound [C] gives compound [D] which upon ozonolysis yields formaldehyde and acetaldehyde. Identify the compounds [A], [B], [C] and [D].
