What is the minimum age requirement for obtaining a CCW license in Ohio?

In order to obtain a CCW (carrying a concealed weapon) license in Ohio, an individual must be at least 21 years old. Option A, 18 years old, is incorrect because that is the minimum age for obtaining a regular concealed carry license in Ohio, but not for a CCW license specifically. Options C and D, 25 years old and 30 years old, are also incorrect as there is no specific age requirement for a CCW license in Ohio. Therefore, the correct answer is B, 21 years old.
