Dr. Hegsted argues that just as polio vaccine is given to every person to protect the few who might actually contract polio, mass dietary change is needed to protect the significant number who are susceptible to the life- threatening effects of press eating habits.

Really terribly tough one.......what's the source? doesn't adhere to the rules, so when you choose the option, you just have to pick what you think is the best of the lot using only what you know.
I'd have gone with C if it were a real test, suspiciously though. "which" does not have a preceding comma, and so the extra information presentation is bad.
A on the other hand is a terrible idiom - Just as X, so Y is the correct idiom. The given sentence is undiomatic. Although, there's a rule that "Just as" can be replaced with "in the same way that", using "so" makes the sentence clearer.
D evidently is wrong, the intent is twisted, "while" is replaceable with "as long as" in this particular context.
B is wrong as well, "...that like..." sounds horrendous on the ears.
E is hopelessly wrong because of the gerund "the giving".
Because, I'd strongly eliminate A, B, D and E with the above reasons, I'd have gone with C.
I am AWESOME and it's gonna be LEGENDARY!!!
