Detailed Solution

The above statement is True.
Conductors allow electricity to pass through them. Carbon (in the form of graphite) is a nonmetal that also conducts electricity. The thin black core of our pencil is called pencil lead, and it is formed of graphite, an electrical conductor. Because the human body is a poor conductor of electricity, it only conducts electricity to a small extent.
