(D) Periodic acid $(HIO_4)$ cleaves the $C-C$ bond in vicinal diols,$\alpha$-hydroxy ketones,and $\alpha$-hydroxy aldehydes.In the given compound $HOCH_2-C(=O)-CH(OH)-CH_2OH$:$1.$ The $C_1-C_2$ bond cleavage gives $HCHO$ (from $CH_2OH$) and a carboxyl group at $C_2$.$2.$ The $C_2-C_3$ bond cleavage converts the $C_2$ group to $CO_2$ and the $C_3$ group to an aldehyde.$3.$ The $C_3-C_4$ bond cleavage converts the $C_3$ group to $HCOOH$ and the $C_4$ group to $HCHO$.Thus,the products are $HCHO$ $(H_2C=O)$,$HCOOH$,and $CO_2$.
