Massachusetts' gun laws require safe storage of firearms. Which of the following best describes this requirement?

The requirement for safe storage of firearms in Massachusetts emphasizes that firearms must be stored in a manner that prevents unauthorized access, particularly by children or individuals who may pose a danger to themselves or others. The law specifically mandates that firearms should be stored unloaded and locked. This approach significantly lowers the risk of accidental discharges and unauthorized use of the firearm.

In contrast, the other options do not align with the law's intent to promote safety. Storing firearms loaded, even when locked, increases the risk of accidents, while allowing owners the discretion to store them however they see fit does not provide the necessary safeguards. Therefore, the correct answer reflects the clear and structured guidelines set forth to enhance the security and safe handling of firearms in Massachusetts.
