The correct answer to this open question is the following.
Although there are no options attached, we can say the following.
The term means including everyone in attacks and destruction of war to dampen morale and to hurt every part of a country, not just the soldiers, is the total war.
This is a horrible concept during the war, that has been used many times in human history. The goal of total war is to inflict pain, suffering, and total destruction of people and property in a country, in order to win the war and dominate the enemy. Troops do not touch their hearts in total war. They do not respect the life of citizens, women, and children. They destroy everybody and everything in order to win the war and humiliate the other army and nation.
