SC:Comparison

[YidanX684]

According to a survey of graduating medical students conducted by the Association of American Medical Colleges, minority graduates are nearly four times more likely than are other graduates in planning to practice in socioeconomically deprived areas.

A. minority graduates are nearly four times more likely than are other graduates in planning to practice
B. minority graduates are nearly four times more likely than other graduates who plan on practicing
C. minority graduates are nearly four times as likely as other graduates to plan on practicing
D. it is nearly four times more likely that minority graduates rather than other graduates will plan to practice
E. it is nearly four times as likely for minority graduates than other graduates to plan to practice

I can cross off D,E, because the pronoun is not substitute right answer.
BUT as for A,B,C, I can not pick the right one.
help,please.
thanks in advance.

Please read that entire thread.

If you still have questions after reading the whole thing, please post specific questions on that thread.

"I can't decide among A, B, and C" isn't something we can really answer. It's too vague; we don't know where you're actually having problems with those choices.
What do you understand?
What don't you understand?
Which construction(s) in those choices is/are the source of the trouble?
What, specifically, don't you understand about the construction(s) in question?
Etc.

Thanks.
