Final answer:
The correct option is c. Rupert Brooke is the WWI poet from the options provided who did not survive the war; he died in 1915 due to an infection.
Step-by-step explanation:
The World War I poet whose work we read and did not survive the war is Rupert Brooke. Among the poets listed -- Wilfred Owen, Siegfried Sassoon, Rupert Brooke, and Robert Graves -- it is Rupert Brooke who died during World War I; he died of an infection in 1915. The remaining poets, Wilfred Owen died just a week before the war ended in 1918, but Sassoon and Graves did survive the war.
Poets like Wilfred Owen and Siegfried Sassoon were known for their work that displayed the inhumanity and suffering of the war, with no heroic charges celebrated in their stanzas. These poets, along with visual artists like Käthe Kollwitz, conveyed the misery and horror of World War I powerfully and helped fuel criticism of what was seen by many as a pointless and devastating conflict.
