Correct choice: tanks, poison gas, ambulance.

Explanation: Tanks and chemical weapons (poison gas) were developed and first deployed on a large scale during World War I. Motorized ambulances were also expanded and modernized during the war. The other items (airplanes, balloons/zeppelins, automobiles, submarines) existed before WWI, though many were rapidly improved and widely used in the conflict.
