Answer:
D. Unfunded mandate.
Step-by-step explanation:
An unfunded mandate is one where states are required and expected to perform certain duties without any provision of financial support from the federal government. This federal regulation or statute expects states or local bodies to execute certain actions but also provides no monetary support to them for the very act.
Unfunded mandates are majorly controversial or unfair in that companies or states are expected to do certain work but not be refunded or supported. This means there is no aspect of help, like working under someone's orders but spending one's own money.
