Final answer:
The correct answer is D. a public enemy. Insurance cannot be provided to a public enemy as it goes against the principles of insurability. Insurability is based on the concept of risk, and a public enemy does not have an insurable interest or be subject to a loss that can be compensated through insurance.
Step-by-step explanation:
The correct answer is D. a public enemy. Insurance is a contract between an insurance company and the insured, where the insurance company agrees to compensate the insured in the event of a covered loss or damage. However, insurance cannot be provided to a public enemy because it goes against the principles of insurability.
Insurability is based on the concept of risk. To be insurable, a person or entity must have an insurable interest and be subject to the possibility of a loss. A public enemy, who poses a threat to the safety and well-being of society, cannot have an insurable interest or be subject to a loss that can be compensated through insurance.
