The correct answer is C. Tenant.
Insurable interest is a legal concept that requires an insured person to have a financial interest in the property or life that is being insured. This means that the insured person must stand to lose something if the property is damaged or the life is lost.
In the case of a tenant, the tenant does not have an insurable interest in the property. This is because the tenant does not own the property and does not have a financial stake in its well-being. If the property is damaged or destroyed, the tenant will not suffer any financial loss.
The other options, spouse, business partner, and self, all have insurable interest. A spouse has an insurable interest in the life of their spouse because they would suffer financial loss if their spouse died. A business partner has an insurable interest in the life of their business partner because they would suffer financial loss if their business partner died. And a person has an insurable interest in their own life because they would suffer financial loss if they died.
Insurable interest is an important concept in insurance law because it helps to ensure that insurance policies are not used for fraudulent purposes. If someone did not have an insurable interest in the property or life that they were insuring, they could potentially collect a large sum of money from the insurance company without having suffered any real loss. This would be unfair to the insurance company and to other policyholders.
