(B) The reaction involves the thermal decarboxylation of geminal dicarboxylic acids (malonic acid derivatives). In the first reaction,the reactant is a cyclopentane ring with two $-CO_2H$ groups at the same carbon (geminal) and two $-Br$ atoms at the adjacent carbons. Upon heating,one $-CO_2H$ group is lost as $CO_2$,resulting in a single product $x$ (a monocarboxylic acid). In the second reaction,the reactant is also a geminal dicarboxylic acid on a cyclopentane ring,but with $-Br$ atoms in a different stereochemical configuration (trans-like relative to the ring). Decarboxylation of this molecule can lead to two different stereoisomers for $y$ due to the presence of chiral centers and the specific geometry of the ring. Therefore,the number of possible products for $x$ is $1$ and for $y$ is $2$.

The products obtained in the given reactions are shown below. The number of possible products for $x$ and $y$ is:
