(B) The given compound is $1,2,4,5$-tetramethylcyclohexa-$1,4$-diene. It has two chiral centers at positions $1$ and $4$ (if we consider the substituted carbons). However,due to the symmetry of the molecule,we analyze the stereoisomers: $1$. The $cis,cis$-isomer (meso compound,optically inactive due to a plane of symmetry). $2$. The $trans,trans$-isomer (chiral,exists as a pair of enantiomers). $3$. The $cis,trans$-isomer (meso compound,optically inactive due to a center of symmetry). Thus,there are a total of $3$ stereoisomers possible.

List-$I$ (Pair of Compounds)	List-$II$ (Isomerism)
$A$. $n$-propanol and Isopropanol	$(I)$ Metamerism
$B$. Methoxypropane and ethoxyethane	$(II)$ Chain Isomerism
$C$. Propanone and propanal	$(III)$ Position Isomerism
$D$. Neopentane and Isopentane	$(IV)$ Functional Isomerism

The number of all the possible stereoisomers formed by the given compound is
