Correct option is D) The neutron has a neutral charge, which made it impossible to discover using previous experiments with positive and negative charges.

Explanation:

The protons are the positively charged particles of an atom. The electrons are the negatively charged particles of an atom. As both the particles carry some kind of charge i. e either positive or negative, hence their discovery was easier.

The neutrons are the part of an atom which are neutral and do not carry any charge. Hence, their discovery took a more longer time as compared to the discovery of electrons and protons.
