Schools organizing events

Schools organizing events have adopted new rules that aim to identify students of different schools and that seat them in a separate area
(A) to identify students of different schools and that seat them
(B) to identify students of different schools and seat them
(C) to identify students of different schools for seating

Please explain each choice.

The issue seems to be one of parallelism. Your first option connects "that aim to" and "that seat them." This suggests that the rules "aim" and "seat" the students. B sets "seat them" parallel to "identify," so that these are both the "aims" of the rules. This is probably the most correct. C is a bit awkward, as it makes "seating" the purpose of the identification; this series of phrases is not perfectly clear. Overall, I'd say B is the best here, though you'd probably have to rewrite it a bit to make the overall meaning perfectly clear.

Thanks for your reply. I'm still little confused. Please clarify the following.

1. Is not the sole purpose of identification is to seat them in a separate area (what C states)
2. grammatically '....for seating....' is correct or it has to be '...to seat...'

Thanks in advance.

"identify students for seating" is awkward. While "seating" might be one of the ultimate goals of the new rules, it doesn't make much sense to say "identify for seating."

"for seating" and "to seat" could each be correct, but it would depend on the context, and here neither is correct. In general, the choice of preposition follows from the words before the preposition, not after.
