问题补充：

A. turn to
B. look for
C. deal with
D. talk about
答案：
(答案→)A. turn to
B. look for
C. deal with
D. talk about
解析：turn to 意为“求助于”；whom to turn to是“疑问词+不定式”作doesn’t know的宾语,根据所提供的情景“She’s having a lot of trouble with the new computer”和并列连词but可判断出 “她不知道向谁求助”。look for 意为“寻找”；deal with意为“处理”；talk about意为“谈论”。
