gmatusa2010, dont think D and C are not parallel...

(C) female students, as opposed to male students, are more concerned about job discrimination.
changes the meaning... firstly does not establish the comparison between female studs concern and male studs concern..this rather establishes a comparison between the 2 types of student - male and female .

(D) female students are more concerned about job discrimination than male students are concerned ..concerned for one is redundant and secondly.. if you were to repeat concerned.. you should have repeated "concerned about job discrimination"
which again would have been redundant but grammatically correct
So ,
female students are more concerned about job discrimination than male students are concerned about job discrimination

Comparison:

In case of comparison, the elements that are compared MUST be parallel.

Example:

I am taller than Rana (is).

here,
I am =Clause = NOUN + VERB.

AND

Rana (is) = Clause =NOUN + VERB.

Two clauses have been compared.

Again:

I like pizza more than noodles.

Here, the comparison is between NOUN, PIZZA, and NOUN, NOODLES.

We can easily prephrase the correct sentence by looking to the non-underlined portion of the sentence.

The skeleton of the sentence:

Female students are more concerned than male students.

Clause + Than + Another Clause.

in the original sentence, we see only NOUN Phrase.

We need another clause.

Now look for the options that have clause after than.

-> A and E can easily eliminated.

--> D is not good for using "concerned", and C is not good for comparing only the two nouns, rather than two clauses.

Answer is definitely B.

A survey of American business schools concludes that female students are more concerned about job discrimination than male students.
What does the sentence mean: This sentence has ambiguous meaning due the manner in which the comparison is stated. From this sentence we do not know which of the following comparisons are true - Female students are more concerned about job discrimination than:
1: they are concerned about male students
2: male students are
Thus, the correct answer choice should explicitly state one of the two comparisons above.
What are the errors in the original sentence: The original sentence has no grammatical errors but it has meaning error as stated above.
Now we will eliminate the answer choices that have similar meaning error.

(A) female students are more concerned bout job discrimination than male students.
Incorrect. Eliminated due to meaning error
(B) female students are more concerned about job discrimination than male students are.
Correct. This sentence is correct since it explicitly states the comparison.
(C) female students, as opposed to male students, are more concerned about job discrimination.
Incorrect. This sentence does not express the comparison clearly. It is not clear who is being compared with female students. Read this similar sentence:
Mary, as opposed to Amy, is taller. In this sentence, we do not know in comparison to whom is Mary taller. All we know is Amy is not taller than that unknown person.

(D) female students are more concerned about job discrimination than male students are concerned.
Incorrect. This sentence is more wordy than the correct choice B. If two subjects have same verbs and in same tense, then it is more precise and preferable to use the helping verb for the second occurrence of that verb as done in Choice B.
(E) female students are more concerned about job discrimination than their male counterparts.
Incorrect. Eliminated due to meaning error

If you see very closely then you can eliminate C, because it uses 'as' to compare nouns.

My question is, if C were like

female students, Unlike male students, are more concerned about job discrimination

would be right or wrong?
