Respuesta :
Inhibit the flow of electrons because insulators are those substances which are bad conductor of heat and electricity.
Answer: Inhibit the flow of electrons.
The electricity flows when the electrons flow. A conductor conducts electricity when electrons flow through it. An insulator is a bad conductor of electricity because it doesn't allow the flow of electrons. So, the correct option is that an insulator has a property that it inhibits the flow of electrons.
