I hear sam has gone to Qingdao for his holiday Oh,how nice!Do you know when he
a left
b was leaving
c has left
d had left

首先 c,d 是完成时,表示做过什么事.汉语中就有“了”这个字,比如,我把地给拖了,我把作业写完了（I have done my homework),都用完成时.但这里 Do you know when he left 指的是你知道他什么时候走的吗?没有“了” 所以不用完成时,于是就排除c,d
其次,b 是过去进行时,指的是刚刚你正在干啥.通常有个“在”字.比如我刚刚在打网球（I was playing tennis).但在这里你知道他什么时候走的吗?,没有“在”字,也不是说他刚刚正在走,于是就不对.
最后只剩A了.left 是 leave 的过去式,表示走这个动作.所以合适.
