The correct explanation for why a World War I-era poster like the one mentioned would have been produced is:
B. To convince young men to enlist in the military during the war effort.
During World War I, propaganda posters were commonly used to boost recruitment numbers by appealing to patriotism, duty, and a sense of heroism. The poster's aggressive language like "DESTROY THIS MAD BRUTE" was aimed at evoking emotions of anger and a desire for revenge against the enemy. The call to action "ENLIST" was meant to persuade young men to join the military and contribute to the war effort.
These posters played a crucial role in shaping public opinion and mobilizing support for the war. By portraying the enemy as a "mad brute" and emphasizing the need for enlistment, such posters were powerful tools in influencing individuals to take action and support the war cause.
