(D) The thermal decomposition of esters (pyrolysis of esters) proceeds via a cyclic transition state ($E_i$ mechanism). In this reaction,the $\beta$-hydrogen atom from the alkyl group is removed by the carbonyl oxygen of the ester group. The $\beta$-hydrogen that is more acidic (or leads to the more stable alkene) is preferentially removed. In the given ester,the alkyl group is a $2$-methylcyclopentyl group. The $\beta$-hydrogens are available at the $C_1$ and $C_3$ positions of the cyclopentyl ring. Removal of the $\beta$-hydrogen leads to the formation of $3$-methylcyclopentene as the major product,as it follows the cyclic transition state mechanism.
