Which amongst the following compounds has the highest acid strength?

An organic compound $\mathrm{A}$ with molecular formula ${\mathrm{C}}_3{\mathrm{H}}_6{\mathrm{O}}_2$, which is a colourless liquid at room temperature with unpleasant odour, onnreaction with Phosphorous trichloride gives compound $\mathrm{B}$. Compound $\mathrm{B}$ on treatment with dimethyl cadmium gives compound $\mathrm{C}$, which when treated with sodium hypoiodite gives yellow colour precipitation. Identify compounds $\mathrm{A}, \mathrm{B} \mathrm{and} \mathrm{C}$ and write the sequence of the chemical reactions involved.

Given below are two statements, one is labelled as Assertion $\mathbf{A}$ and the other is labelled as Reason $\mathbf{R}$.
Assertion $\mathbf{A}$: A solution of the product obtained by heating a mole of glycine with a mole of chlorine in presence of red phosphorous generates chiral carbon atom.
Reason $\mathbf{R}$: A molecule with $2$ chiral carbons is always optically active.
