(D) The reaction involves the electrophilic addition of $HBr$ to the given polycyclic alkene. First,the proton $(H^+)$ from $HBr$ attacks one of the double bonds to form the most stable carbocation intermediate. In this structure,the formation of a tertiary $(3^\circ)$ carbocation is possible at the bridgehead position,which is more stable than secondary $(2^\circ)$ carbocations. Assuming no carbocation rearrangement,the bromide ion $(Br^-)$ then attacks this $3^\circ$ carbocation to form the final product. Based on the provided solution image,the product corresponds to the addition of $Br$ at the tertiary bridgehead carbon.

Which of the following bromides is the major product of the reaction shown below,assuming that there are no carbocation rearrangement?
