我知道你为什么你弄不清楚,是不是老师给你们说过,修饰人用过去分词,修饰物是现在分词?所以你觉得修饰的是人,要用B.
其实这只是一个大概的记法,你会经常遇到特殊的情况,考试的时候经常这样考.所以我给你介绍个好一点的方法.就是你看题目的意思.如果是..的意思就用过去分词,如果是令人、让人.的意思就用现在分词,而题目的意思是他的失败让他的爸爸觉得他是一个让（令）人失望的人.是让人、令人失望,所以用现在分词,而不是过去分词.希望对你有所帮助

没有绝对的修饰人与修饰物之分，用那个词主要是看主动与被动的关系！如果把boy换成物就知道为什么了吧？希望对你有帮助

disappointing是指令人（比如这里指他爸爸）失望的...
disappointed是指一个人自己“失望的”心情、情绪
