During a thunderstorm with lightning, the safest action to take regarding electrical equipment is to unplug all devices. This is because a lightning strike can send a high voltage surge of electricity through power lines and into electrical devices, potentially causing damage or starting a fire. It is not safe to continue using electrical equipment during a thunderstorm. Only using battery-operated devices (C) may provide some protection, but it is still possible for a lightning strike to damage these devices. Checking wiring for safety (D) is also not recommended during a thunderstorm, as it involves coming into contact with electrical equipment. Therefore, unplugging all electrical equipment (B) is the best and safest option during a thunderstorm with lightning.
