Which of the following is not a type of OASDI benefit?

OASDI stands for Old-Age, Survivors, and Disability Insurance, which is a comprehensive program administered by the Social Security Administration that provides benefits to eligible individuals in three main categories: retirement, disability, and survivor benefits.

Retirement benefits are provided to individuals who have reached a certain age and have accumulated enough work credits through their earnings. Disability benefits are available to those who become disabled and are unable to work, while death or survivor benefits are paid to the dependents or beneficiaries of workers who have passed away, helping to support them financially after a loss.

Investment benefits, however, do not fall within the scope of OASDI. This is because OASDI is primarily concerned with social insurance benefits rather than investment returns or profits. It operates based on a pay-as-you-go system funded through payroll taxes, rather than through investment income.

Therefore, the identification of investment benefits as not being an OASDI benefit is correct, as OASDI strictly relates to the aforementioned benefits focused on retirement, disability, and survivors, without any connection to investments.
