Solution

The correct option is A They are good conductors thus may carry charges.
Metal pipe-lines for carrying water and electrical wires are good conductors and carry charges. If a lightning strikes the building, there may be chance of electric shocks getting spread through those due to leakage and this could be dangerous for life.
