Laws have been passed in parts of South Africa, governments either tax shoppers who use plastic bags or fine companies that hand them out.
A. which
B. where
C. as
D. what

A. which(答案→)B. whereC. asD. what解析：考查定语从句关系词的选择。根据句子结构可知该句为非限制性定语从句，先行词parts of South Africa 在定语从句governments either tax shoppers who use plastic bags or fine companies that hand them out中作地点状语。故选择where=in which
