Who is eligible to apply for an Ohio CCW permit?

Any Ohio resident over the age of 21 with no felony convictions is eligible to apply for an Ohio CCW permit. This means that option B, military personnel stationed in Ohio, is incorrect because it excludes non-residents who are also eligible to apply. Similarly, option C, non-residents who work in Ohio, is also incorrect because it excludes Ohio residents who do not work in the state. Option D, anyone over the age of 18, is incorrect because the minimum age to apply for a CCW permit in Ohio is 21, not 18. Therefore, the best and most accurate answer is A.
