None of them is correct.

b. Battle of Leyte Gulf was in Oct, 1944
c. Hiroshima and Nagasaki was in Aug, 1945
d. Battle of Midway was in Jun, 1942

The Battle of Midway is the closest answer, but it was not in the Spring of 1942.
But I agree that the Battle of Midway was the turning point of the War in the Pacific. Japan lost 4 aircraft carriers and approx 300 fighter aircraft, which meant Japan lost its air supremacy over the western Pacific theater as early as in the mid 1942, only six months after the Pearl Harbor. The Battle of Midway was a disastrous defeat for Japan.

As Adm. Yamamoto, the commander of Japanese Navy said (prior to the war), "It is impossible for Japan to carry out the war with the US more than 6 months," Japan was doomed to be defeated as a result of the Battle of Midway.
