Step-by-step explanation:
The phrase 'Germany rolls up its sleeves, looks at France, and punches Belgium' corresponds to option a. Germany executing the Schlieffen Plan.
The Schlieffen Plan was a strategic German offensive plan developed before World War I. It involved attacking France through Belgium instead of their shared border, with the aim of quickly defeating France and then redirecting forces to engage Russia. The phrase describes Germany's aggressive action of invading Belgium as part of the larger plan to execute a quick offensive against France.
For example, in 1914, at the beginning of World War I, Germany's military crossed into Belgium as part of the Schlieffen Plan, seeking to outflank French defenses and swiftly advance towards Paris.
