What is the minimum age to apply for an Ohio CCW permit?

In Ohio, the minimum age to apply for a CCW (Concealed Carry Weapon) permit is 21 years old. Option A, 18 years old, is incorrect because it is the minimum age to purchase a handgun in Ohio, but not necessarily to carry one. Option B, 19 years old, is also incorrect because it is the minimum age to carry a handgun in a vehicle without a permit, but not to obtain a CCW permit. Option D, 25 years old, is incorrect because it is not the minimum age for a CCW permit in Ohio.
