The effort needed by all sectors of a society during a conflict is called the Holocaust. total war. rationing. a skirmish.

A Holocaust was the genocide on the Jewish population during the Second World War - not what the question is asking for.

Rationing refers to the division of goods among people - it can be during the time of conflict but it was also present during socialism

A skirmish is a short battle.

So the best answer is a total war: a war in which the whole society is involved and needs to give up on some things for the war effort!
