Key Points:
Electrophilic Aromatic Substitution (Bromination with Br$_2$/FeBr$_3$).
Activating groups (-NHCOR) direct ortho/para and increase ring reactivity.
Deactivating groups (-COR) direct meta and decrease ring reactivity.
Substitution usually occurs on the most activated ring.
For N-phenylbenzamide, the -NHCOPh group activates the aniline ring (ortho/para), while the -CONHPh group deactivates the benzoyl ring (meta).
Product (C) is expected based on standard rules, but the key indicates (A).
