if you check you will get 3 combinations, because the question says that the two bars taken are not of the same type.

The six different combinations are CB and NB,CB and MB,NB and CB,NB and MB,MB and CB and finally Mb and CB. But CB and NB and NB and CB are same, same with NB,MB and MB,NB and CB,MB and MB,CB...Thus there are only 3 unique options available...
