选 3
这里的先行词是xiao hua 是人,引导词whom在从句中充当宾语,所以用宾格.
从句中主语是you,谓语是came across,而宾语是whom,即是指xiao hua.
当引导词在从句中充当主语的时候就用who,充当宾语的时候就用whom,但是现代语法who也可以用做宾语.

whom只能用于做宾语的情况。
who在现代英语立即可以指代主语也可以做宾语。
现行词xiaohua在后面的定语从句中作came across的宾语，即“I came across Xiaohua in the street list month.”所以用whom

3,who是主语 whom是作宾语；这里，come across偶遇的是作宾语，所以要选3
