The median of the combined set will lie between the medians of A & B respectively... so ans is a, b & c...

However, check the question or its source.. GMAT has only 1 correct ans for problem solving

From my understanding, when we combine two sets with medians M1 and M2, the resulting median should be between M1 and M2. Applying the same here, the resulting median can only be between 7 and 13.

Thus, each of a,b and e cannot be median.

Do correct me if I am wrong.
