    D it may spoil the wiring Correct Answer Incorrect Answer

    Solution

    Using water for putting out electric fires is risky, as the firemen can be electrocuted by the water jet. Water is a good conductor of electricity, and, the electric current flows through the water jet directly into the hands of the person who is holding the water- hose, resulting in immediate electrocution
