关于unlike的一道语法题

Unlike emergency calls that travelthrough regular telephone lines, where they thus automatically

inform the operator of the location andphone number of the caller, cellular calls require emergency

operators to determine the location ofthe caller.

(A) lines, where they thus automaticallyinform the operator of the location and phone number of the

caller, cellular calls require emergencyoperators to determine the location of the caller

(B) lines and thus automatically informthe operator of the location and phone number of the caller cellular calls require emergencyoperators to determine the location of the caller

(C) lines, thus automatically informingthe operator of the location and phone number of the caller,

the location of the caller on a cellularphone has to be determined by the operator

(D) lines, and thus automatically informthe operator of the location and phone number of the caller,

emergency operators have to determine thelocation of the cellular phone caller

(E) lines, thus automatically informingthe operator of the location and phone number of the caller,

emergency operators receiving a cellularcall have to determine the location of the caller

不是说like和unlike之后只能接名词么。。可是这儿emergency calls that我理解是可以。可是还能接个and thus automatically inform我就费解了。。如果是这样。and之后难道就不用加that么。。不加that 不是会变成后面有个句子。。囧。。大牛们帮帮忙吧
