3. In a sports competition, the Red and White teams each have 5 players participating. The scoring method is: players score points for their team based on their ranking in the competition, with the first place scoring 1 point, the second place scoring 2 points, and so on, and each player's score is unique. The team with fewer points wins. The possible winning score is ( ).
(A) 29
(B) 28
(C) 27
(D) 13
3. (C).

Both teams scored a total of $1+2+\cdots+10=55$ points. Therefore, to win, a team needs to score at most $\left[\frac{55}{2}\right]=27$ points. Since each team must score at least $1+2+3+4+5=15$ points, the answer to this problem can only be 27 points.
