b. America destroyed four Japanese carriers and drove Yamamoto into retreat.
Explanation:
During the battle, US forces stop a Japanese attack on Midway Atoll, losing one aircraft carrier and one destroyer, and sinking four aircraft carriers and one heavy cruiser to the Japanese.
The battle was a decisive victory for the Americans, widely regarded as the most important naval battle in the Pacific campaign in World War II. The battle permanently weakened the Imperial Japanese Navy, especially with the loss of four aircraft carriers and over 200 irreparable, experienced Navy pilots.
Both countries suffered casualties in the battle, but Japan was powerless to rebuild its naval forces, while at the same time the US shipbuilding and training program for new pilots provided rapid replenishment.
