Correct Option: B. To exploit resources and establish economic dominance Detailed Explanation: The primary objective of colonial administration in the 19th century was largely driven by economic interests. European powers, during this period, sought to expand their empires and increase their wealth through the acquisition of colonies. Here’s a step-by-step breakdown of why option B is the correct answer:

1. Economic Motivation: The 19th century was marked by the Industrial Revolution, which created a demand for raw materials to fuel factories in Europe. Colonies were seen as sources of these raw materials, such as cotton, rubber, minerals, and other resources. The economic exploitation of these resources was a primary goal of colonial powers.
2. Establishment of Trade Routes: Colonies were strategically located to facilitate trade routes. By controlling these territories, colonial powers could ensure that they had access to valuable resources and could also establish markets for their manufactured goods. This economic dominance was crucial for the growth of European economies.
3. Infrastructure Development: Colonial administrations often built infrastructure, such as railways and ports, not primarily for the benefit of local populations but to extract resources more efficiently and transport them back to the colonizing country. This further illustrates the exploitative nature of colonial rule.
4. Political Control: To maintain economic dominance, colonial powers often imposed political control over the colonies. This included establishing governments that favored colonial interests and suppressing any movements toward independence or self-governance.
5. Cultural Justifications: While colonial powers often justified their actions with rhetoric about civilizing missions or cultural exchange, these were largely secondary to the economic objectives. The idea of "civilizing" local populations was often used to mask the exploitative practices that were actually taking place.

Why the Other Options Are Wrong:

• Option A: To promote local self-governance and independence This option is incorrect because colonial administrations typically sought to maintain control over their colonies rather than promote self-governance. In fact, many colonies experienced significant resistance movements against colonial rule, which were often met with repression.
• Option C: To foster cultural exchange and mutual respect While there were instances of cultural exchange, the dominant narrative of colonialism was one of superiority and domination. The imposition of European culture often led to the suppression of local customs and traditions, rather than a mutual respect or exchange.
• Option D: To provide humanitarian aid and support local populations Although some colonial powers claimed to provide humanitarian aid, the primary focus was on resource extraction and economic gain. Humanitarian efforts were often superficial and aimed at justifying colonial rule rather than genuinely supporting local populations.

Revision Summary:

• The primary objective of 19th-century colonial administration was economic exploitation and dominance.
• Colonies were sources of raw materials and markets for European goods, driven by the Industrial Revolution.
• Infrastructure was developed primarily for resource extraction, not for the benefit of local populations.
• Colonial rhetoric often masked the exploitative nature of their rule, focusing on control rather than promoting independence or mutual respect.
