(B) The reaction of $N$-bromosuccinimide $(NBS)$ with $KOBr$ (which provides $Br_2$ and $OH^-$) involves the hydrolysis of the imide ring. The $OH^-$ attacks one of the carbonyl carbons,leading to the opening of the succinimide ring. This results in the formation of $4$-amino$-4-$oxobutanoate (or its protonated form depending on pH),which is represented by the structure in option $B$.
