Final answer:
Among the options listed, Social Security is the major public assistance program that does not provide in-kind support but instead offers cash-based assistance to retirees and disabled individuals.
Step-by-step explanation:
Major public assistance in-kind programs include a range of services and support, but not all of these programs provide aid in the same way. Programs such as food stamps (now known as the Supplemental Nutrition Assistance Program or SNAP), school lunches, and Medicaid offer support in the form of services or goods directly to individuals or families in need. On the other hand, Social Security provides a different kind of support, consisting of regular cash payments to eligible retirees and disabled people, making it an example of cash-based assistance rather than an in-kind program.
