Final answer:
The claim that high-voltage wires are wrapped in insulating material is false; air serves as the insulation while the wires are supported by insulating connectors.
Thus the corret opction is:b
Step-by-step explanation:
The statement that high-voltage wires connected to tall metal-frame towers are held aloft by insulating connectors and that these wires are wrapped in an insulating material is false.
High-voltage transmission lines are indeed supported by insulating connectors to prevent electricity from grounding through the support tower.
However, contrary to what the question suggests, these wires are not wrapped in insulating material.
The air around the wires serves as the insulating medium.
The high-voltage wires are capable of carrying electricity efficiently over long distances with minimal insulation due to the significant space between the wires and any grounded surface.
The complete question is:Building controls such as locked doors and security guards are the inner most layer of protection for restricting access to computing resources.
