The correct answer is B. The atomic bomb forced the Japanese to surrender.

To arrive at this answer, we need to understand the historical context of the atomic bomb's use during the final stages of World War II. The bombings of Hiroshima and Nagasaki in August 1945 led to the almost immediate surrender of Japan, which effectively ended the war in the Pacific.

To determine that the atomic bomb achieved something that conventional military force had not yet done, we can consider the previous efforts made by the Allies to defeat Japan. Before the atomic bomb, the Allies had been engaged in a long and costly campaign in the Pacific, battling Japanese forces island by island.

Conventional military force had managed to push the Japanese back and regain some territory, but Japan showed no signs of surrendering. The use of the atomic bomb was seen as a last resort to bring about a swift end to the war and avoid the need for a costly invasion of the Japanese mainland.

By dropping the atomic bombs on Hiroshima and Nagasaki, the devastating power of these weapons was made clear to the Japanese, prompting them to surrender. The bombings marked the first and only use of nuclear weapons in warfare to date.

Therefore, the correct answer is B. The atomic bomb forced the Japanese to surrender, achieving what conventional military force had not yet accomplished.
