We have five friends: A, B, C, D, and E. Let's use the given conditions to arrange them:
1. \( A \) is sitting next to \( B \), so they must sit together.
2. \( C \) is sitting at one of the ends, so either \( C \) is at the leftmost or rightmost position.
3. \( D \) is sitting between \( A \) and \( E \), so \( D \) must be between \( A \) and \( E \).
4. \( E \) is sitting to the right of \( D \), so \( E \) must be to the right of \( D \). Using these conditions, the seating arrangement will be: \[ C, A, B, D, E \] Thus, the person sitting in the second position is \( A \).
Thus, the answer is \( \boxed{A} \).
Four teams – Red (R), Blue (B), Green (G), and Yellow (Y) – are competing in the final four rounds of the Inter-School Science Olympiad, labeled Round A, Round B, Round C, and Round D. Each round consists of one match between two teams, and every team plays exactly two matches. No team plays the same opponent more than once.
