The correct Answer is:
**Step-by-Step Solution:** 1. **Understanding the Composition of a Lead Pencil:** - A lead pencil is commonly thought to contain lead, but this is a misconception. The core of a lead pencil is primarily made of graphite. 2. **Identifying the Main Component:** - Graphite is a form of carbon and is the primary material used in the pencil's writing core. It is known for its ability to leave marks on paper. 3. **Role of Clay:** - In addition to graphite, clay is mixed with graphite to create the pencil lead. The clay acts as a binding agent and helps to control the hardness of the pencil. 4. **Clarifying the Misnomer:** - Despite its name, a lead pencil does not contain any lead (Pb). The term "lead" originates from the historical use of lead in writing instruments, but modern pencils use graphite instead. 5. **Conclusion:** - Therefore, a lead pencil is composed of graphite and clay, with graphite being the main component responsible for writing. **Final Answer:** A lead pencil contains graphite and clay. ---
