If someone wants to get an insurance policy to protect others only, the type of insurance they would typically get is life insurance. Life insurance is designed to provide financial protection for the beneficiaries or dependents of the policyholder in case of the policyholder's death. This means that if the insured person passes away, the life insurance policy will pay out a sum of money to the designated beneficiaries.
Unlike health insurance, which covers medical expenses for the insured individual, or disability insurance, which provides income protection in the event of disability, life insurance specifically focuses on providing financial support to the loved ones or dependents of the policyholder after their passing.
So, in the context of protecting others financially in the event of the insured person's death, life insurance is the type of policy someone would choose.
