Enantiomers are non-superimposable mirror images of each other.

A good heuristic is to assign absolute configurations, and find the pair with the same orientation/configurations.

puu.sh

From that data, we can determine that #("A")# and #("B")#, as well as #("C")# and #("D")# are enantiomers.

Out of your choices, it seems as though "A&B" is correct.
