The correct option is B Cover it with insulation tape
Electric wires are covered in rubber to prevent the electricity from causing any harm or damage. When the rubber cover is broken or torn, the metal wire is exposed. Sameer should not touch the wire with our bare hands or even with any metal object like spoon, because it can result in a harmful electric shock. Also, dipping the wire in water is equally dangerous, as it can result in a shock too. Instead, he should cover the exposed part of the wire completely with a rubber insulation tape. This would prevent electric shock to him or to any other person in the house.
