What is the primary purpose of an accelerated benefit rider in a life insurance policy?

The primary purpose of an accelerated benefit rider in a life insurance policy is to provide financial support to the insured who has been diagnosed with a terminal illness. This rider allows the policyholder to receive a portion of the death benefit while still alive, typically when facing significant medical challenges, such as anticipated long-term care needs. This can alleviate some of the financial burdens during a critical time and allow the insured to use the funds as they see fit, whether for medical expenses, home modifications, or other necessary costs.

The other choices provided do not accurately represent the function of an accelerated benefit rider. The enhancement of the policy's face value upon death, waiving premium payments during a disability, or offering investment options are not aligned with the intended use of an accelerated benefit rider. Instead, these choices reflect different types of insurance provisions or riders that serve separate purposes within the spectrum of life insurance policies.
