Solution

The correct option is C Both A and R are true and R is the correct explanation of A.
Rubber is an insulator. Insulators are the materials which do not allow the electric current to pass through them.
Hence, covering of wires with rubber is safe as it prevents us from getting electric shocks by not allowing electricity to pass through them.

Therefore, both A and R are true and R is the correct explanation of A.
