Final answer:
Long-term care insurance can be terminated under certain circumstances, such as non-payment of premiums. The government's role, as seen in the Patient Protection and Affordable Care Act, is limited to influencing the market rather than mandating eternal policy validity. Option d is correct.
Step-by-step explanation:
LTC insurance, or long-term care insurance, can indeed be terminated under certain circumstances, contrary to the options presented that it cannot be terminated due to being a lifetime policy, the insured's unchanging good health, or government mandate.
The government, through actions like the Patient Protection and Affordable Care Act, can influence the availability of insurance for certain groups, but political decisions do not eliminate the challenges of moral hazard and adverse selection within insurance markets.
Insurance policies, including LTC insurance, have specific terms and conditions under which they can remain in force or be terminated. For instance, non-payment of premiums or fraud could lead to the termination of an LTC insurance policy. Therefore, the correct answer to the question is: 'It can be terminated under certain circumstances.'
