In a widespread power outage where cell towers are down, what is the most reliable way for a household to receive official emergency broadcasts and weather alerts?

✓ Correct Answer: Option B

A battery-powered or hand-crank NOAA weather radio is designed to receive official emergency broadcasts directly from the National Weather Service, even when power and cell services are out. Most modern landline phones require electricity, commercial radio stations may go off-air, and walkie-talkies have limited range for contacting authorities.
