The correct choice identifies the three major components of modern firearms as the barrel, action, and stock.

The barrel is the elongated steel tube through which the bullet travels when the firearm is fired. It is essential for accuracy and performance, influencing factors such as the bullet's velocity and trajectory. The action is the mechanism that loads, fires, and ejects the cartridges, effectively controlling the gun's operation. It can include several different systems like bolt-action or semi-automatic actions. Lastly, the stock serves as the part of the firearm that is held against the shooter’s shoulder or body, providing stability and control while aiming and shooting.

By understanding these components, one can better appreciate how a firearm operates and its various functionalities, which is crucial for safe handling and operation as emphasized within the CFSC.
