Final answer:
Forced labor camps were the least deadly for Jews compared to concentration, death, and transit camps, as they offered some prisoners the possibility to survive due to their labor utilisation, despite high mortality rates and inhumane conditions.
Step-by-step explanation:
The type of camp that was the least deadly for Jews during the Holocaust was the forced labor camp. While death camps, such as Belzec, Sobibor, Treblinka, and Auschwitz-Birkenau, were explicitly designed for mass extermination, resulting in the death of Jews typically within hours of arrival, forced labor camps were different. In these camps, prisoners were ruthlessly used for labor, which, despite high mortality rates, allowed for more possibilities of survival compared to the immediate killings in death camps. Transit camps were temporary holding facilities, but they often ended up sending prisoners to either death camps or forced labor camps; and concentration camps, although they did utilize prisoners for labor, still had a significant death toll due to harsh conditions and executions.
During the Holocaust, the concentration camps served as both labor and death camps, with prisoners detained under inhumane conditions and many perishing due to the harsh treatments. Nevertheless, the death toll in concentration camps was not as high as in extermination camps, where the singular purpose was the mass murder of prisoners, usually just hours upon their arrival. The survival rate in extermination camps, barring a few revolts and extraordinary circumstances, approached almost zero.
