The correct answer is C. The Battle of Guadalcanal was a significant victory for the Allies because it put Japan on the defensive.
Explanation:
The Battle of Guadalcanal took place between August 7, 1942 and February 9, 1943, around the island of Guadalcanal in the Pacific front of World War II.
For the first time, the US forces went on the offensive against Japan, which had occupied much of the western Pacific since December 1941. From August 1942 to February 1943, the island of Guadalcanal was the focal point of very heavy fighting on land, water and air. The supply routes to Guadalcanal were fiercely contested. Both sides lost aircraft carriers, several cruisers and numerous smaller ships. In the course of the conflict over Guadalcanal about 50 ships from both sides were sunk by air raids and naval battles. On the American side, at the end of the clashes, the number of sailors killed at sea exceeded the number of soldiers killed in months of tough jungle fighting.
The Guadalcanal battle can be seen as the turning point of the war: after the first victory at the Midway Atoll, the Allies took over the initiative, and this battle was the confirmation of the Allied advantage in the Pacific.
The losses suffered during the battle were no longer recoverable by Japan. Following the loss of aircraft carriers and pilots at Midway, the fleet suffered additional irreplaceable losses in its military and mainly in cargo ships.
