Friction reduction in firearms must come with a lubricant that stays clean and thin enough to form a smooth protective film. Light, pistol-rated lubricants are designed to stay at the right viscosity under normal use, so they reduce wear without attracting dirt or breaking down into sticky, gummy residue. Heavy greases tend to trap grit and powder fouling, and they can polymerize into a gummy layer that slows movement or causes jams. Oil-based or water-based options can leave inappropriate films or wash away in dirty or wet conditions, making them less reliable. So the best choice is light, pistol-rated lubricants, which minimize gummy buildup by avoiding the heaviness and dirt-attracting properties of thicker greases.

Deadly force means using force that is likely to cause death or serious injury. The correct option matches this exactly by stating death or great bodily harm. The other choices don’t fit because they describe outcomes that don’t reach that level of harm: minor injuries and non-lethal injuries aren’t at the deadly level, and property damage only involves harm to property with no bodily injury. Including both death and great bodily harm covers the full threshold described for deadly force.

The main idea is how wide the buckshot pattern spreads after leaving the muzzle. In a 2 3/4-inch shell loaded with 00 buck, the pellet cloud tends to be about 20 inches across at common close ranges. This is because the nine pellets start close together but diverge as they travel, producing a spread that grows with distance. At farther ranges, the pattern would get larger—roughly around 40 inches at about 25 yards and even wider beyond that—so the 20-inch spread best matches typical close-range use. The larger numbers would imply much longer distances than what’s usually considered when estimating the approximate spread.

The key idea is cushioning recoil. The rubber butt plate at the end of the shotgun’s stock is designed to absorb some of the energy felt when the gun fires, reducing felt recoil and making it more comfortable and controllable to shoot. That specific piece is called a recoil pad. Choke refers to the muzzle device that tightens or widens the shot spread, not the cushioning at the stock end. The stock is the main frame you shoulder, not the cushioning piece itself. A muzzle brake also deals with gas from the muzzle to damp recoil, but it’s located at the barrel’s end, not at the butt. So the term that matches the rubber pad designed to reduce recoil is recoil pad.
