Answer:
c. too much pride can bring a downfall
Explanation:
Both of these characters were showing pride in one way or another. Don was being overly proud of being smart that people started doubting if he was actually smart- this would be his "downfall"
Tom was confident that his team would win, but they didn't. He was so full of anticipated pride while he daydreamed about holding the trophy that he missed what would have been a winning pass which would be his "downfall"
In summary, both of these characters' downfall was their pride, even if the downfall wasn't something grand or serious, or even if it hadn't happened all the way yet.
Hope this helps!
