Is a permit required to purchase a firearm in Utah?

In Utah, a permit is not required to purchase a firearm. Utah law does not have a firearm permit requirement for individuals looking to purchase any type of firearm, whether it is a handgun, rifle, shotgun, or assault weapon. Therefore, option B is the correct answer. The other options are incorrect because they suggest that a permit is required for all firearms (option A), only for handguns (option C), or only for assault weapons (option D), which is not in accordance with Utah state laws.
