portable extinguishers that use water stored under pressure must have a minimum effective discharge range

10 feet
20 feet
30 feet
60 feet

Explanation:

Identify extinguisher rating location

Portable fire extinguishers display their alphanumeric classification and rating information directly on the faceplate (the main label on the front of the extinguisher shell). This allows users to quickly identify which classes of fire (e.g., A, B, C) the unit is rated to extinguish.

Determine water extinguisher discharge range

According to standard fire protection specifications (such as NFPA 10 standards for portable fire extinguishers), a standard stored-pressure water extinguisher (typically 2.5 gallons) has a minimum effective discharge range of 30 feet (approximately 9 meters) to allow the operator to apply water from a safe distance.
