再请教大全635题 （以前讨论过，没定论）

1.        Several recent studies suggest that a child born into a family whose members have allergies will probably themselves develop allergies following the onset of a minor viral infection.

(A) a child born into a family whose members have allergies will probably themselves develop allergies

(B) children born into families whose members have allergies will probably themselves develop allergies

(C) a child born into a family the members of which have allergies will probably develop an allergy

(D) in those families where members have allergies, children will probably develop allergies themselves

(E) children born into a family in which there are allergies will themselves probably develop an allergy

争议在B and C. 大全选B, 理由是C which 指代 family, which 指代人， 是ets 大忌

我选C， 因为B的themselves指代不清，可以是children， 也可以是members

以前的讨论统统看过了，一直没有定论，
