Question

An alkene $A$ on ozonolysis yields acetone and an aldehyde. The aldehyde is easily oxidised to an acid $B$. When $B$ is treated with bromine in presence of phosphorus yields a compound $C$ which on hydrolysis gives a hydroxyl acid $D$. This acid can also be obtained from acetone by the reaction with hydrogen cyanide followed by hydrolysis. Identify the compounds $A,B,C$ and $D$
