Solution

The correct option is B Air is a bad conductor of electricity.
Air is a bad conductor of electricity and those wires are placed away from human activities. Hence, there is no substantial loss of energy or lives during the flow of electricity in the overhead electric wires. Hence there is no requirement for any insulation.
