Respuesta :

Option (a), which states that trench warfare was widely used in World War I, is the right response.

Why did trench fighting occur so frequently in World War One?

Due to the horrendous casualties incurred in open combat, trench warfare was immediately adopted. Within four months, soldiers on all fronts had started building trenches because they were a particularly effective way for infantry to defend themselves against powerful weapons.

Why was trench warfare utilized, and what did it entail?

On the Western Front, trenches were prevalent. The purpose of long, narrow trenches cut into the ground near the front during World War I was to shield troops from machine gun fire and artillery attack from the air. Typically, these trenches were created by infantry soldiers who would occupy them for weeks at a time.
