A. Lead
B. Platinum
C. None of these
D. Graphite
🧠 Explanation:
- Graphite is commonly used as the positive electrode (cathode) in a dry cell battery.
- It acts as a conductor that collects electrons generated from the chemical reactions inside the cell.
- Its stability and excellent electrical conductivity make it ideal for this role.
- Dry cells are widely used in flashlights, toys, and remote controls, with graphite playing a key internal role.
