(B) In option $B$,the starting material $(S)-3$-methylpent-$1$-ene contains a chiral center at $C-3$. When $HBr$ adds across the double bond via an electrophilic addition mechanism,a new chiral center is formed at $C-2$. Since the original chiral center at $C-3$ remains unchanged,the addition of $Br^-$ can occur from either face of the carbocation intermediate,leading to two products that have the same configuration at $C-3$ but different configurations at $C-2$. These two products are diastereomers of each other.

Which of the following reactions results in the formation of a pair of diastereomers?
