California Firearms Safety Certificates (CAFSC) Practice Exam

Informing an adult when encountering a firearm is crucial primarily for safety reasons. Adults are generally responsible and knowledgeable about the proper handling of firearms. By securing the firearm, an adult can ensure that it is stored safely and not accessible to children or anyone who may not know how to handle it responsibly. This action helps prevent potential accidents, misuse, or injury that could occur if a firearm is left unsecured, particularly in the hands of someone who is untrained.

The other options do not emphasize safety or responsible behavior. Showing off or allowing exploration can lead to dangerous situations, while validating feelings of excitement does not address the need for safety and responsibility when it comes to firearms. Thus, the imperative to inform an adult aligns directly with the importance of securing the firearm and preventing hazardous incidents.
