A. Zinc
B. Lead
C. Carbon
D. Tin
Check Answer
The correct answer is C. Carbon.
The “lead” in lead pencils is actually a mixture of graphite and clay. Graphite is a form of carbon that is a good conductor of electricity and has a high melting point. It is also soft and brittle, which makes it ideal for use in pencils. The graphite/clay mixture is inserted into a wooden casing to create the familiar writing tool. So, the element used in lead pencils is carbon.
