The strengthening of British control over Assam after 1857 led to:

Increased exploration and mapping expeditions into Arunachal Pradesh
Introduction of new administrative systems in tribal areas
Gradual extension of British influence
All of the above

The correct answer is: d) All of the above

After the Indian Rebellion of 1857, the British East India Company was dissolved and the British government took direct control of India. This led to a strengthening of British control over Assam, which was then a province of British India.

One of the consequences of this was increased exploration and mapping expeditions into Arunachal Pradesh, which was then a largely unexplored region. The British were interested in Arunachal Pradesh for a number of reasons, including its strategic location and its potential for economic development.

The British also introduced new administrative systems in tribal areas in Assam. These systems were designed to bring the tribal areas under British control and to promote economic development.

Finally, the British gradually extended their influence into other parts of Assam. This was done through a combination of military force and diplomacy.

The strengthening of British control over Assam had a significant impact on the region. It led to increased exploration and mapping, the introduction of new administrative systems, and the gradual extension of British influence. These changes had a profound impact on the lives of the people of Assam.

Here is a brief explanation of each option:

  • Increased exploration and mapping expeditions into Arunachal Pradesh: The British were interested in Arunachal Pradesh for a number of reasons, including its strategic location and its potential for economic development. In order to better understand the region, they conducted a number of exploration and mapping expeditions. These expeditions helped the British to learn more about the geography of Arunachal Pradesh, its people, and its resources.
  • Introduction of new administrative systems in tribal areas: The British introduced new administrative systems in tribal areas in Assam. These systems were designed to bring the tribal areas under British control and to promote economic development. The new systems included the establishment of courts, schools, and hospitals. They also included the introduction of new taxes and laws.
  • Gradual extension of British influence: The British gradually extended their influence into other parts of Assam. This was done through a combination of military force and diplomacy. The British used their military to conquer new territory and to suppress rebellions. They also used diplomacy to negotiate treaties with local rulers. As a result of these efforts, the British gradually extended their control over most of Assam.
