Yep. Thats correct. A is an alkene, C has bromine not chlorine and D has 2 chlorine atoms.

Members of a homologous series differ by -CH2-, this includes functional groups. Ie as in this case, chloropropane and chlorobutane differ by -CH2-.

(Now wait for someone to give you (and me) an awesome explanation of this with better phraseology...)

Take Chemology answers and exams in general with a grain of salt. They're pretty terribly made from my experience.
