Final answer:
Harry lost the match against Hufflepuff because he was hit by a Bludger.
Explanation:
Harry lost the match against Hufflepuff because he was hit by a Bludger. In the game of Quidditch, Bludgers are flying balls that try to knock players off their broomsticks. The objective of the game is for the Seeker to catch the Golden Snitch, which ends the match, but that did not happen in this case. So, option d) 'He was hit by the Golden Snitch' is incorrect.
