Answer:
A
Step-by-step explanation:
The material that would best suit Hardin electronic corporation's need would be a non-metal.
Non-metals are naturally occurring substances or materials that lack the properties of metals. In other words, non-metals are poor conductors of heat and electricity, unlike metals.
Solid non-metals are, therefore, used as insulators in the design of materials. Hence, the best material for Hardin electronic corporation to use that will insulate the phone and protect their users from electric shock would be a non-metal.
The correct option is A.
