The United States used atomic bombs in the attack on Hiroshima and Nagasaki in 1945 to end the war. Option B is correct.
During the final stage of World War II, the United States detonated two nuclear weapons over the Japanese cities of Hiroshima and Nagasaki on August 6 and 9, 1945. An American B-29 bomber dropped the world’s first deployed atomic bomb over the Japanese city of Hiroshima.
The explosion wiped out 90 percent of the city and immediately claimed the lives of 80,000 people.
