Explanation:
Using gas during World War I (WWI) changed the concept of warfare significantly. It represented a shift from traditional warfare tactics, which had previously involved troops facing each other in open battlefields. The introduction of chemical warfare with weapons like poison gas transformed battlefields into areas of prolonged trench warfare, where advancing was as dangerous as defending because of the threat of being subjected to gas attacks.
These new methods of combat increased the dangers for non-combatants, leading to higher civilian casualties. The psychological impact of gas warfare, alongside the physical harm, necessitated protective measures that redefined logistical support and combat preparedness. The use of gas also marked an emphasis on technology and industrial capacity in warfare, stepping beyond the limits of conventional arms to encompass chemical sciences.
In summary, using gas during WWI led to D) All of the above: It marked a radical departure from prior warfare strategies, introduced new forms of conflict with chemical weapons, and resulted in greater civilian suffering. The war became one of attrition, with advancements in technology determining the scale and methods by which battles were fought.
