What is the minimum age to possess and transport a handgun in Indiana without supervision?

In Indiana, the minimum age to possess and transport a handgun without supervision is 18 years of age. This means that a person must be at least 18 years old to legally carry a handgun without supervision. Options B, C, and D are incorrect because they all state ages that are higher than 18 years, which would not be considered the minimum age. Option B, 21 years, is the minimum age to purchase a handgun, but not for possession and transportation. Option C, 16 years with parental consent, is also incorrect as parental consent does not waive the minimum age requirement for possession and transportation. Additionally, option D, 25 years, is incorrect because it is also a higher age and does not meet the criteria for the minimum age in Indiana.
