The problem faced by the Ford administration was D. Stagflation.
Stagflation is a situation where there is a combination of high inflation and high unemployment along with slow economic growth. During Gerald Ford's presidency, the United States experienced a period of economic difficulty characterized by stagflation. This posed a significant challenge for his administration as it required balancing policies to tackle both inflation and unemployment simultaneously. Stagflation can be particularly challenging to address because the usual remedies for inflation (such as raising interest rates) can worsen unemployment, and vice versa.
To summarize, the Ford administration had to grapple with the complex issue of stagflation, which demanded nuanced economic policies to combat both high inflation and high unemployment.
