(D) Heating $\beta$-keto acids or substituted malonic acids leads to decarboxylation (loss of $CO_2$).For a compound to become achiral after decarboxylation, the resulting product must have a plane of symmetry, a center of symmetry, or be a molecule where the chiral center is destroyed (i.e.,the carbon atom becomes bonded to two identical groups).In option $(D)$, the starting material is $2$-ethyl-$3$-oxobutanoic acid derivative. Upon heating, it undergoes decarboxylation to form $2$-butanone (or a similar derivative depending on the specific structure). Specifically, the structure in $(D)$ is $2$-ethyl-$3$-oxobutanoic acid. Upon decarboxylation, the chiral center at the $\alpha$-carbon (which has $H$, $Et$, $CO_2H$, and $COCH_3$ groups) loses the $CO_2H$ group and gains an $H$ atom. If the resulting product has two identical groups attached to the central carbon (e.g.,two $H$ atoms or two $Et$ groups), it becomes achiral.Looking at the provided solution image, the transformation in $(d)$ results in a molecule where the central carbon is bonded to $H$, $Et$, $Me$, and $H$ (if the $CO_2H$ is replaced by $H$). Wait, the image shows the product of $(d)$ as having $H$, $Et$, $Me$, and $H$ attached to the central carbon, making it achiral because it has two identical $H$ atoms.

The compound$(s)$, capable of producing an achiral compound on heating at $100^{\circ} C$ is/are:
