Sentence Correction

Although some parents believe that the local all-girls school should begin to admit boys, others claim that girls would participate actively in class only if they had all-girls classes.

A)that girls would participate actively in class only if they had all-girls classes
B)that girls will only participate actively in a class if it is all-girls
C)that girls will only participate actively in an all-girls class
D)that girls would participate actively only in a class that were all-girls
E)that girls in all girls-classes will participate actively in that situation only

[spoiler]OA:C[/spoiler]

Agree with OA

All girl class is better sounded than a class if it is all-girls or in a class that were all-girls, thus eliminate B & D

in A) the use of had is wrong
in E) the sentence is wordy

So, C is the best answer

Just my 2 cents

A wrong because correct usage is
if he won he would distribute
if he had won he would have xxxx

E awkward
B and D wrong because in a class that were all-girls is wrong

C has wrongly placed modifier "only". It says girls will ONLY participate and wont do anything else. So changes the meaning. Experts please comment

I too eliminated B & C on the basis of wrong modification by "only" in the sentences. I go with D.

I chose A for the same reason...Would be great if anyone could explain c?

I am also confused between A and C.

we are talking about the simple future and I don't think so usage of would is correct.....
