(A) $NBS$ ($N$-Bromosuccinimide) is a reagent used for allylic or benzylic bromination via a free radical mechanism.In the given structure,the carbon atom at the bridgehead position (the carbon shared by the two non-aromatic rings) is a tertiary carbon,but it is not allylic or benzylic.Substitution at the bridgehead carbon is highly unfavorable due to the strain involved in forming a planar radical intermediate at that position (Bredt's rule).Therefore,the product shown in option $A$ (where $Br$ is attached to the bridgehead carbon) is the least likely to form.
