Ford's economic policy had the following effect on the economy:
Option C: Inflation went down, but unemployment remained high.
Explanation:
1. During Ford's presidency, his economic policy aimed to curb inflation by implementing measures such as WIN (Whip Inflation Now) campaign, which encouraged cost-cutting and reducing consumer demand.
2. As a result, inflation did decrease to some extent due to these efforts.
3. However, despite the decrease in inflation, unemployment remained high during his term, indicating that his policies did not have a significant impact on reducing unemployment rates.
Therefore, Option C is the most accurate description of the effect Ford's economic policy had on the economy.
