Awhom,这里 I had a talk with the pretty girl,the pretty girl 是先行词,the man同时作为.whom I had a talk with句子的宾语,只人的,所以用whom

答案是A。
whom指代的是前面的the pretty girl ，所以B不能选，which不能指代人。
选whom而不是who是因为whom是talk with的宾语。
不选D的原因是talk with sb.是固定搭配，with是不能省略的。

选A。首先指代人有whom不用which，其次have a talk with sb是固定搭配，介词with不能省略。
