Given the circumstances surrounding Roosevelt's " Pearl Harbor Address to the Nation," what was most likely his speech's primary purpose?

A To summarize other instances of Japanese aggression in addition to the attack on Pearl Harbor
B To make it clear the country was in great danger as a result of the actions taken by Japan
C To issue a strong response to the attack on Pearl Harbor by declaring war on Japan
D to reassure the American people that the nation was still safe after the attack on Pearl Harbor

Pearl Harbor marks the enter of the United States to WWII in an active and fighthing way, prior to this the States had no real reason to enter the war according to its laws, there had been no attacks nor damages on american soil or army bases around the globe, this was the perfect reason to enter the war and help the allies. President Roosevelt´s speech then tried:

C To issue a strong response to the attack on Pearl Harbor by declaring war on Japan.
