Question

president carters second economic plan proposed
new regulations for businesses.
controlling wages and consumer pricing.
a new method for reducing stagflation.
establishing a national banking system.

Explanation:

President Carter's second economic plan, introduced in 1978, focused on voluntary wage and price controls to combat the high inflation and stagnation (stagflation) facing the U.S. economy at the time. The other options are incorrect: new business regulations were not the core proposal, the plan was a specific approach to stagflation rather than a "new method" label, and a national banking system was established long before Carter's presidency.

Answer:

controlling wages and consumer pricing.
