Which of the following does not respond to Fehling's solution test and haloform reaction but shows Cannizzaro's reaction?

$CH_3-CH_2-OH$ $\xrightarrow{PCC} A$ $\xrightarrow{HCN} B$ $\xrightarrow[\Delta]{H_3O^{+}} C$
Compound $C$ is:

The major products of the following reaction are:

Compound $(A)$,$C_6H_{12}O_3$,when treated with $I_2$ in aqueous sodium hydroxide gives a yellow precipitate. When $(A)$ is treated with Tollens' reagent,no reaction occurs. When $(A)$ is hydrolysed and then treated with Tollens' reagent,a silver mirror is formed in the test tube. Compound $(A)$ will be

$B$. $KOI$ is a reducing agent.
$C$. $\alpha, \beta$-unsaturated methylketone will give iodoform reaction.
$D$. Isopropyl alcohol will not give iodoform test.
$E$. Methanoic acid will give positive iodoform test.
