Why would the phrase "controlling wages and prices" complete this diagram? O The war weakened the U. S. economy, making controls necessary.
O The wartime economy required cooperation from workers and industry.
O The entry of women into the workforce created the need for controls
The lack of jobs during the war led to lower wages and falling prices.

B). The wartime economy required cooperation from workers and industry.

Explanation:

At the time of war, the United States economy was deeply affected as well as transformed by World War II while the government was aiming to minimize its impact on the citizens of the state. In order to so, the government urged both people working in the industries as well as the industries where they were working to be a part of this effort and cooperate which later came in the form of 'controlling of wages and prices.' This helped in keeping the wages at a constant level for the wartime which helped the government to reduce the damage and impact caused by WWII. Thus, option B is the correct answer.
