Explanation:

To determine who decided to use the atomic bomb, we recall historical events. During World War II, after the death of Franklin D. Roosevelt, Harry Truman became president. It was Harry Truman who made the decision to drop the atomic bombs on Hiroshima and Nagasaki. Dwight D. Eisenhower was involved in other military and political roles later, Franklin D. Roosevelt died before the atomic bomb was used, and Douglas MacArthur was a military commander, not the one who made this decision.

Answer:

A. Harry Truman
