Final answer:
General revenue sharing is the form of federal assistance that provides money to state governments with no strings attached, offering maximum flexibility in the use of the funds.
Step-by-step explanation:
The form of federal assistance that provides money to state governments with no strings attached is known as general revenue sharing. This type of federal assistance was in place from 1972 to 1986 and allowed state and local authorities to have the most discretion in how the funds were used, with minimal federal restrictions.
Unlike categorical grants or block grants, which come with more specific guidelines or purposes for the money, general revenue sharing presented an opportunity for subnational governments to allocate funds according to their own priorities and needs.
