Final answer:

Step-by-step explanation:
The two native Indian hierarchical systems strengthened and exploited by the British colonies were the caste system and the Zamindari system.
The caste system is a Hindu practice of placing people in social layers with similar occupations, privileges, and status. It was made more rigid and antagonistic by the British during colonial rule, with education and job opportunities being offered to select caste groups. The Zamindari system, on the other hand, was a land tenure system introduced by the British where landlords were granted rights and control over large tracts of land. This system further consolidated the power of the local elite and often led to exploitation of the lower classes.
