Yes, you are correct. After 1941, when Germany occupied most of Europe during World War II, the German officials in those areas typically relied on local collaborators to help run the occupied territories. This means that local individuals who cooperated with the German authorities played a significant role in the administration, governance, and enforcement of German policies. Collaborators often assisted with tasks such as maintaining order, implementing German policies, and carrying out various administrative functions. So, your choice of C: Local collaborators is indeed the correct answer in this case. Well done!
