因为逗号不能连接两个句子,所以后一个小分句不可以是完整的句子结构.
所以A不对.B不对,两个人用both不用all.C也不对,如果都不是护士,后面的nurse就应该是单数,而不是复数.实际上用them就是错的,因为这样就成了一个独立的句子了.
whom是宾格指代词,这样第二个小分句就成为修饰sisters的宾语从句,结构上才正确.意思也符合句意.

注意：后面的那个句子中动词是复数形式。所以选A、D中的一个。而前面的sisters不是主语，那么就用D，即who的宾格形式

D.
从句。
ABC都是完整的句子。 逗号不能代表新句子。

d
work 为原型则必然选择有both 或all的选项。 前提为两个妹妹所以选了有both的A D 而后面有逗号隔开两句，确定选择D
