(C) In Kolbe's electrolysis,the electrolysis of potassium salts of vicinal dicarboxylic acids results in the formation of an alkene.The reaction proceeds via a free radical mechanism:$CH_3-CH(CO_2K)-CH(CO_2K)-CH_3 \xrightarrow{	ext{electrolysis}} CH_3-CH=CH-CH_3 + 2CO_2 + H_2 + 2KOH$Between the possible geometric isomers,the trans-isomer is more stable due to reduced steric hindrance between the methyl groups.Thus,the major product is trans-But$-2-$ene.

$CH_3-CH(CO_2K)-CH(CO_2K)-CH_3 \xrightarrow{\text{electrolysis}} (A) \text{ (Major)}$
The major product $(A)$ of the above reaction is:
