Step-by-step explanation:
The correct answer is (c) At least 30 days. An insurer is typically required to provide at least 30 days advance notice if they intend to cancel a homeowner's insurance policy for a reason other than nonpayment of premium. This allows the policyholder to find alternative coverage or address any issues that might lead to the cancellation. For example, if an insurer determines that the insured property poses a higher risk due to changes in the property's condition or the insured has violated certain policy terms, they must give the policyholder at least 30 days' notice before canceling the policy.
