The correct answer is option 'D) Criminal Tribes Act'.

Explanation:
The British passed the Criminal Tribes Act in 1871 in addition to the Forest Regulation Act. This act was specifically aimed at labeling the adivasi (indigenous) groups that rebelled against the British as criminals. Here is a detailed explanation of the Criminal Tribes Act:

1. Historical Context:
During British rule in India, there were many instances of adivasi groups resisting their policies and rebelling against their oppressive rule. The British authorities considered these rebellions as a threat to their control and sought to suppress them.

2. Criminal Tribes Act, 1871:
The Criminal Tribes Act was passed in 1871 to systematically control and suppress the adivasi groups that were considered "criminal" by the British authorities. The act classified specific tribes and communities as inherently criminal, irrespective of individual behavior or actions.

3. Criminalization of Adivasi Groups:
The act categorized various adivasi communities as "criminal tribes" based on their traditional occupations such as hunting, gathering, and shifting cultivation. It labeled their way of life as criminal and deemed them as prone to criminal activities.

4. Restrictions and Surveillance:
Under the Criminal Tribes Act, the labeled communities were subjected to strict restrictions and surveillance. They were required to report to the local authorities regularly, seek permission to move from one place to another, and were closely watched by the police.

5. Loss of Livelihood and Social Stigma:
The act also targeted the traditional occupations of these communities, such as hunting and gathering, by criminalizing them. This resulted in the loss of their livelihoods and pushed them towards poverty and destitution. Moreover, the communities were stigmatized and faced discrimination due to their criminal label.

6. Rehabilitation and Settlement:
The act aimed to reform the labeled communities by forcing them to adopt settled agricultural practices and abandoning their traditional way of life. They were encouraged to settle in specific areas designated as "rehabilitation" or "reformation" colonies.

7. Repeal and Aftermath:
The Criminal Tribes Act was repealed in 1949 after India gained independence from British rule. However, the legacy of the act continued to affect the labeled communities, as they still faced social and economic marginalization due to the stigma associated with their criminal label.

In conclusion, the Criminal Tribes Act passed by the British in 1871 was an oppressive law that labeled adivasi groups as criminals, targeting their traditional way of life and livelihoods. It resulted in the surveillance, restrictions, and stigmatization of these communities, leading to long-lasting social and economic consequences.
