What is the eligibility requirement for survivors’ benefits under OASDI?

The eligibility requirement for survivors’ benefits under Old-Age, Survivors, and Disability Insurance (OASDI) is that benefits are only available if the worker was fully insured. In order for survivors to receive benefits, the deceased worker must have earned enough credits through their work history to qualify for the OASDI program. This generally means that the worker must have worked for at least 10 years, which contributes to being fully insured, but it’s specifically the status of being fully insured that is crucial for survivor benefits to be available.

Survivors depend on the insured status of the deceased worker, as benefits cannot be disbursed unless this condition is met. Therefore, focusing on the necessity for the worker to be fully insured underscores the foundation of the program, thereby making it the correct answer with respect to the eligibility for survivors' benefits. Other answers either misrepresent the specifics of eligibility, such as limiting it to only surviving children or suggesting that income alone determines eligibility, which is not the case in this context.
