The compound $\left(\mathrm{A}\right) {\mathrm{C}}_6{\mathrm{H}}_{12}{\mathrm{O}}_3$, when treated with ${\mathrm{I}}_2$ in aqueous sodium hydroxide gives yellow precipitate. When $\left(\mathrm{A}\right)$ is treated with Tollen’s reagent no reaction occurs. When $\left(\mathrm{A}\right)$ is hydrolysed, and then treated with Tollen’s reagent, a silver mirror is formed in the test tube. Compound $\left(\mathrm{A}\right)$ will be
