The best answer is C. Einstein was horrified to think that Hitler might build an atomic bomb, so he wanted the United States to make one first. While Einstein was a renowned pacifist, he wrote a letter to President FDR, urging him to begin work on an atomic bomb so Hitler would not be the first. He later regretted his letter but thought the result was still better than if Nazi Germany had created it first.
The verified answer is wrong. I had this on an exam. The correct answer would be B.) After spurring U.S. efforts to build an atomic bomb, Einstein worked to eliminate the arms race as a cause of war. The proof that I am correct is in the photo below. Have a great week to whoever sees this answer. I'm sorry if you got this wrong in the past but, I posted this to help anyone who hasn't answered this question yet.
