Final answer:
Dadaism rose as an anti-war, anti-bourgeois protest against the rationalist and nationalist ideas that led to World War I, focusing on irrational thought and irrationality in its 'anti-art' to challenge cultural norms and conformity which is option B.
Step-by-step explanation:
The statement that best explains how Dadaism related to World War I is: B. Dadaism blamed logic and reason for causing World War I and rejected those ideas in favor of irrational thought and silliness. This form of art arose as a reaction against the rationalism and nationalist mentality which led to the devastation of the war. Dadaists viewed the war as the product of a society gone awry, being corrupted by capitalism, conformism, and violence. They believed that in an age of advanced machinery and warfare, humanity was being lost. The movement protested this societal breakdown with a form of 'anti-art' that scorned cultural and intellectual conformity and was intensely anti-war and anti-bourgeois.
The use of non-traditional media like collage, photomontage, and assemblage in Dada art was a direct challenge to the values of the time. By incorporating mundane and everyday objects into their works, Dada artists created pieces that were meant to offend, to be destructive, and to destabilize the cultural status quo. Their purpose was not to create aesthetically pleasing work but to criticize life, government, and institutions, and to reveal the absurdity and irrationality of the post-war world.
