Could you please tell us what kind of work ------- you have

in which = where三个选项都不能选,此题无解。原因：A项；首先排除B项：in which = where ,in which 只有视作一个整体时才表示where ,若用 in which 引导从句,那么先行词work 应该在从句中作状语,可是此时从句的宾语和状语无法连接。若理解为in 原本是跟在experience之后的再次提前到引导词之前即 in + which ,那么先行词work 依然在从句中作状语但是,引导从句的先行词不符合条件。C项：引导词和先行词在从句中所充当的角色相矛盾。结论：三个选项都不选。
