The answer is Blitzkrieg. Blitzkrieg means "lightning war". It is a military tactic that was designed to disorganized enemies in war. During that war on Sept 1, 1939, Germany invaded Poland. They were lead by mobile warfare, like tanks. They had aerial support and soldiers heavily armed with ammunition. They attacked enemy forces with short and powerful attacks and dislocated them by using speed and making them fall for their trip. Because of this strategy, defenders were not able to fight back against their attacks
Yea the correct answer here definitely is D.
If Germany had won the War the British Empire would have surely crumbled. They would either had to accept less then favorable terms of defeat like Germany did in the World War I or even force they would become occupied by the Nazi German forces and the British would had to live under the German boot.
It allowed them fewer ships than the US and Britain limiting the kind of parity they hoped to have on the world stage in terms of naval power.
One of the arguments went that the US and Britain had to have larger navies because of their need to maintain a force in more than one operating theater while the Japanese only had to worry about their side of the Pacific. It wasn't something that made a number of hardcore military types within the Japanese leadership very happy, but they ended up signing the treaty anyway (though refused to renew it in the 1930s).
