Smith set
A pairwise loses to C, so it is certain that all candidates from A through C (A, B, and C) are in the Smith set. However, there is one matchup where a candidate who is known to be in the Smith set loses or ties someone who may or may not be in the Smith set: C loses to D; so D is confirmed to be in the Smith set. Another such matchup can now be seen: D ties with E. So E is added into the Smith set. Because all of A through E beat all candidates other than each other, the Smith set is A through E.
