答案

定语从句的关系词的判断是使用“先行词代入法”,
即把先行词代入定语从句中去,看先行词在定语从句中所占的成分：
若先行词在从句中做主语、宾语或定语则选择关系代词（who/whose/whom/that用于指人,which/that用于指物）；
若在从句中做状语,则选择关系副词（where/when/why）
那么回到这句
in the situation( in which)___people are suffering from diseases related to the pollut
明显是作状语,不能作宾语也不能作主语
而本题中只有D.where 可以作状语.
所以选D.where
