Answer:
option (B)
Step-by-step explanation:
There are two types of materials.
1. Conductors: The materials which can allow the electric current to pass through them easily are called conductors. for example, metals, normal water, etc.
2. Insulators: The materials which do not allow to pass the electricity through them are called insulators. For example, rubber, wood, plastic, etc.
Conductors allow charged particles to flow but insulators stop teh flow of electricity.
