Insulators will:

inhibit the flow of neutrons
allow the flow of electrons
inhibit the flow of electrons

Inhibit the flow of electrons  

Explanation:

An electric current usually consists of electrons moving through a wire.

An insulator prevents the flow of an electric current, so it inhibits the flow of electrons.

inhibit the flow of electrons

Explanation:

As we know that the electrons are moving from the medium then this type of medium is known as conductors while if the medium will resist the flow of electrons then it is known as insulators

So insulating medium will not allow the electrons to move through the medium

So here all the insulating medium will not allow the flow of electrons while all the conductors will allow the electrons to move through it

All the resistors will allow the flow but also the resist the flow of the charge

so correct answer will be

inhibit the flow of electrons

if they have a finite resultant
