Answer:
A. Neutrons have 0 Charge
Step-by-step explanation
Neutrons have no charge for the same reason that plastics (and other insulators don't). They just don't.
"This isn't a great answer, but the thing with charge is that we don't really know what "charge" is. We know that certain "charged" objects will attract some objects, while repelling . We also know that other other "charged" objects will behave the same way, but when the two charged objects are brought together, they repell."
