The correct answer is D: Yes, but only in situations involving the immediate safety of human life or protection of property. According to FCC Part 97.403, amateur station control operators may operate outside their normal frequency privileges only when the communication is directly related to immediate safety of human life or protection of property and when no other means of communication is available. This is a very narrow exception that recognizes that in genuine emergencies, saving lives or protecting property may require using frequencies outside normal privileges. However, this exception is strictly limited to immediate safety situations - it's not for general emergency preparedness, routine emergency drills, or convenience. The key requirements are: (1) immediate safety of life or property protection, (2) no other means available, and (3) it's a true emergency.
