Answer: A: My sister is excited that her swim team earned a championship and that her debate team won its first tournament.
Explanation: In this sentence the common word "that" is used ("that her swim team" and "that her debate team") leading me to believe that A is the answer.
A sounds like the most likely answer, since it shows that she cares for him and wants to do something special for him.
