63. (27901-!-item-!-188;#058&003440)

Unlike emergency calls that travel through regular telephone lines, where they thus automatically inform the operator of the location and phone number of the caller, cellular calls require emergency operators to determine the location of the caller.

(A) lines, where they thus automatically inform the operator of the location and phone number of the caller, cellular calls require emergency operators to determine the location of the caller
(B) lines and thus automatically inform the operator of the location and phone number of the caller, cellular calls require emergency operators to determine the location of the caller

问题，为啥A不好？

因为如果用where从句，那么根据目前句子成分，它是用来修饰regular telephone lines的。。。。
很明显，用where来修饰tele line是不合适的。。。。
