In Indiana, under what circumstance can a civilian legally fire a gun in self-defense?

In Indiana, it is illegal for a civilian to fire a gun in self-defense in most circumstances. However, under the Castle Doctrine, a civilian can legally fire a gun in self-defense if they reasonably believe that there is an imminent danger of death or serious bodily injury to themselves or another person. Option A is incorrect because the feeling of being threatened alone is not enough to justify the use of lethal force. Option B is also incorrect as it implies that a civilian can use lethal force to stop any type of felony, but this is not always the case. Option D is incorrect because it implies that a civilian can use a gun in self-defense anytime, even in situations where there is no immediate danger or threat. Overall, the correct answer is C because it provides the specific circumstances in which a civilian can legally use a gun in self-defense in Indiana.
