Describe the function of a fire hydrant.

The primary function of a fire hydrant is to provide a reliable and readily accessible water source for firefighters during fire suppression efforts. When firefighters arrive at the scene of a fire, they need a significant quantity of water to extinguish the flames quickly and effectively. Fire hydrants are strategically positioned throughout urban and suburban areas to ensure that firefighters can quickly connect hoses and access the water needed for firefighting.

The design of a fire hydrant allows it to be easily operated by firefighters, who can open it to release water under high pressure, drawing from the municipal water supply. This crucial function is vital for effective fire response, as it helps reduce the risk of fire spreading and enables quicker control over the situation. The other options, while including elements related to fire safety, do not reflect the essential and operational role that hydrants play in firefighting efforts.
