答案

答案：C.
1.when引导一个时间状语从句,翻译：当诺姆拜访我家共进午餐时,他把他的假期照片给我看.
主从句成分齐全,为正解.
2.如果用which引导定语从句的话,则楼主需要明白这一点：
关系代词（which等）必须代替先行词（即被定语从句所修饰的名词/代词等）,并在定语从句中充当一定的成分（如果主语/宾语等）.
which代指的先行词就是his vacation photos,将其代入定语从句时,它无法在从句中充当成分,即his vacation photos不能和he visited my house for lunch放在一起构成一个句子.
因为该从句既不缺主语（he）,也不缺宾语（my house）.
3.还是给楼主看一个which引导定语从句的正确例句吧：
Norm showed me his vacation photos (which he had taken in Beijing).
其中,关系代词which代指先行词his vacation photos,在括号中定语从句中充当taken的宾语.
即：which he had taken in Beijing
= he had taken which in Beijing
= he had take his vacation photos in Beijing
从句中含有一个固定搭配：take...photos,意思是“照相”.
