The city of Jericho is a historic city, also mentioned in the Bible, when the Jews, after 40 years of journey through the desert, after leaving Egypt, finally reached the promised land. The city was in the "Canaan" land, according to the Bible, which the Jews led by Joshua, who was leader after Moses, had to conquer. According to historical data, Jericho was located in the valley of the Jordan River, a small village inhabited by a few thousand people, with a stone wall around. There is no evidence of the existence of a ziggurat in the village, which is a stone pyramid, a type of building that dates back to the Sumerian civilization, and which is more characteristic of the Mesopotamian region than Palestine.
I would say that the right answer is C.
Chelmno was the first Nazi camp where gassing was used to murder Jews on a large scale. The site was chosen due to the village’s position in the Warthegau region (previously an area of Western Poland, but now part of Nazi Germany). It was 47 kilometres to the west of the Lodz ghetto where many of the victims came from.
A total of 320,000 people were murdered at Chelmno. These included Jews from the Lodz ghetto and throughout the area, in addition to 5,000 Roma who had been previously sent to the ghetto.
Chelmno consisted of two sites, just two and a half miles apart. The first was located in a large manor house, known as ‘The Palace’.
As there was no railway running through the village of Chelmno, the victims were taken by train to a nearby station. They then walked or were loaded onto trucks to the Chelmno camp reception area.
The first group of victims arrived at Chelmno on 7 December 1941. The following day the first exterminations took place.Throughout 1942. By March 1943 the camp was dismantled because all the Jews in the area had been murdered, except those in Lodz. Hope this helped! :)
