The correct answer is option 'C', which states that the right to cultivate forest land was not a feature of the blandongdiensten system.

The blandongdiensten system was a forced labor system implemented by the Dutch colonial government in the Dutch East Indies (present-day Indonesia) during the 19th and early 20th centuries. It was aimed at exploiting the natural resources of the colony, particularly the forests, for the benefit of the colonial power.

Below are the features of the blandongdiensten system and an explanation of why option 'C' is not correct:

a) Rent exemption:
Under the blandongdiensten system, the indigenous population was exempted from paying rent for the land they cultivated. This was done to encourage the local population to engage in agricultural activities and to ensure a steady supply of agricultural produce for the colonial administration.

b) Free labor and buffaloes for cutting forests:
One of the main purposes of the blandongdiensten system was to exploit the rich timber resources of the Dutch East Indies. The local population was forced to provide free labor and buffaloes for cutting down trees and transporting the timber from the forests to the colonial administration. This labor was often physically demanding and carried out under harsh conditions.

c) Right to cultivate forest land:
Contrary to what option 'C' suggests, the local population did not have the right to cultivate forest land under the blandongdiensten system. The primary objective of the system was to exploit the forests for timber production, and the indigenous people were only allowed to cultivate agricultural land.

d) Free labor for transportation:
Another feature of the blandongdiensten system was the requirement for the local population to provide free labor for the transportation of timber from the forests to the colonial administration. This involved carrying heavy logs over long distances, often on foot or using traditional means of transportation such as carts or rafts.

In conclusion, option 'C' is the correct answer as the right to cultivate forest land was not a feature of the blandongdiensten system. The system focused on the exploitation of timber resources and required forced labor for cutting and transporting timber, rather than allowing the local population to cultivate forest land.
