What are the products formed at the anode during Kolbe synthesis?

In the reaction $CH_3COOH$ $\xrightarrow{LiAlH_4} (A)$ $\xrightarrow{I_2 + NaOH} (B)$ $\xrightarrow{Ag \text{ (Dust)}} (C)$,the final product $(C)$ is

The major product of the following reaction sequence is

The product $(A)$ of the reaction is:

An organic compound $[A]$,molecular formula $C_{10}H_{20}O_2$,was hydrolyzed with dilute sulphuric acid to give a carboxylic acid $[B]$ and an alcohol $[C]$. Oxidation of $[C]$ with $CrO_3-H_2SO_4$ produced $[B]$. Which of the following structures are not possible for $[A]$?

Match the name of the acid from List-$I$ with the source from which it is derived.

$A$. Formic acid	$I$. Rancid butter
$B$. Acetic acid	$II$. Vinegar
$C$. Butyric acid	$III$. Red ants
