Explanation:

Center - fire ammunition has a primer in the center of the cartridge case, while rim - fire ammunition has the primer located in the rim of the casing. Muzzleloaders use different types of ignition systems and not just center - fire. Center - fire is not limited to low - pressure loads and rim - fire cartridges are generally not reloadable due to their construction.

Answer:

D. Rimfire primer is in the rim of the casing.
