Official Solution:

We’ll go for LOGICAL because we can use the logic of median and average.

In a set of consecutive integers, the average and the median are the same. Therefore, (1) is sufficient to give us the median. (B), (C) and (E) are eliminated.

(2) is also sufficient on its own, as we know that the set of consecutive integers goes from 7 to 19: if we know all the numbers in set A, that’s enough in order to find its median. (A) is also eliminated.
