During world war i, the widespread use of the military technology listed above resulted in a. a negotiated peace and a quick end to the war. b. a static war and the adoption of trench warfare. c. a return to traditional tactics and mass infantry attacks. d. a war of movement and the introduction of motor vehicles.

I think it’s B. Because all the others don’t really make any sense the war lasted 4 years and was the turning point in technological advances like tanks gas etc. and it came from both sides which lead to a stalemate aka trench warfare. Hope this helps!
