Answer:
C is the correct answer.
Step-by-step explanation:
The Belgians used the Tutsi minority to enforce their rule in 1926 the Belgians introduced a system of ethnic identity cards to differentiate between Hutus from Tutsis. To colonize Rwanda the Belgians allowed the existing Tutsi monarchs to have control over the Hutus as it helped them to colonize without using their troops. They exploited the Tutsi and Hutu division by giving military support to Tutsi leaders. Due to favoritism by Belgians, the Hutus were left behind and never became the real power holder in politics.
