Question

what was admiral yamamoto’s greatest worry after the attack on pearl harbor?

the japanese pilots did not destroy the oil tanks and fuel storage facilities.

the united states would gather its resources and retaliate.

the american aircraft carriers were not at pearl harbor.

the attack would lead to a declaration of war by germany.

Explanation:

Admiral Yamamoto's greatest worry after the Pearl Harbor attack was that the American aircraft carriers were not at Pearl Harbor. The Japanese aimed to cripple the US Pacific Fleet, and the absence of the carriers meant the US still had a significant naval striking force, which could counter - attack. The other options: not destroying oil tanks was a concern but not the greatest; the US retaliating was a broader outcome, but the immediate worry about the carriers' absence was more pressing in terms of naval power; and Germany's declaration of war was not his primary worry related to the Pearl Harbor attack's aftermath on the US - Japan naval situation.

Answer:

C. The American aircraft carriers were not at Pearl Harbor.
