a) or

d) nor are they
e) nor are not

OA is D

Please help me in resolving this problem.

Here we need "nor" because if we have or because it doesnt give the intended meaning of the sentence.so option a and c are out.
Now we need parallelism for X nor Y.
here X is "many schools do not have" which is NOUN + VERB
therefore we need Y which is NOUN + VERB
and in option D we are having substitute for noun which is "they"

and hence OPTION D is correct.

Also for Option E we are having two negatives which is not required. Both "nor" and "not" are negative.

This is the way I solved this problem. Hope this helps you.

Thanks

Answer is D. Choice B is wrong as it doesn't introduce the subject+verb within the comma's
