For A, it is unlikely that the Br2 bond will break and form Br- and form a reaction with the benzene (carbon ring) which itself highly stable.

It is more likely that other (unstable) part will form reaction first. (ie CH3 and NH2)

For D, the Cu2+ ionic solution (note that it is ions so they are charged and ready to attach to anywhere unstable)

Since -CH3 and -NH2 group on benzene are both 2,4 directing, option A's product is unlikely to be produced. Option A should be the best option to choose out of the 4 and I believe this is a technique for 'A' Levels too - choosing the best possible option. Good luck for your exams! Hope this helps. :)
