Lets use the process of elimination in your question
It can't be A because Lincoln wanted to end the war and have the Southern states join the union as quickly as possible and free all the slaves
It is most likely B because he doesn't really do much to punish he wants to end the war
C and D could easily be eliminated
Japan attacked pearl harbor because of the following:
1. They need to increase their resources in preparation to their expansion in the Asia Pacific.
2. Restrictions. United States is also interested in the Asia Pacific region. They placed economic restrictions to Japan inhibiting Japanese business growth.
3. Expansion. The president of the United States bring the US Pacifc fleet to the Pearl Harbor. This is to give threat to Japan. Japan knoes that war is inevitable their move is to attacked first.
This attacked took 2500 lives of Americans, 18 ships, 300 planes but Japan did not able to exoand in the Pacific and acquisition of resouces did not happen.
Uncertainty because no slaves didn't have rights or a say.
