Which of the following governs the safety of using a shotgun?

The safety check is the correct answer because it is a critical component that ensures the shotgun is functioning properly and is safe to use before engaging in any shooting activities. Conducting a thorough safety check involves inspecting the firearm to ensure that it is unloaded when not in use, verifying that the action works correctly, checking for obstructions in the barrel, and ensuring that the safety mechanism is operational. This process helps prevent accidental discharges and ensures that the firearm is ready for safe handling.

The other choices, while relevant to firearm handling in various contexts, do not specifically focus on the systematic approach needed for ensuring the shotgun's proper safety operation. Point refers to aiming and accuracy, position pertains to the stance of the shooter, and aiming technique involves how to effectively direct the shot. Although these elements are important for shooting proficiency, they do not directly govern the overall safety of using a shotgun in the same way that performing a safety check does.
