Answer: Option (d) is the correct answer.
Explanation:
Insulators are the material that resist the flow of current and therefore, they act as bad conductors of heat and electricity.
For example, rubber, plastic, glass etc are all insulators.
Whereas a conductor is a material that is able to conduct heat and electricity.
Battery is a device that also conducts electricity and resistor is a device that allows limited or specified passage of electricity.
Thus, we can conclude that out of the given options, a material that does not transfer electric charge well is an insulator, is the correct option.
