**Database Query Example**
The query below is run on this data to find pairs where a team’s opponent matches another team’s opponent and the teams are different.
```sql
SELECT S1.Team, S2.Team
FROM Scores S1, Scores S2
WHERE S1.Opponent = S2.Opponent AND S1.Team <> S2.Team;

Based on the query results, identify a valid tuple from the options below:
- a. Lions, Golden Eagle
- b. Golden Eagle, Buffaloes
