Explanations:De-urbanization is a process where a previously urbanized area loses its urban characteristics, often due to economic decline, political changes, or natural disasters. In the context of 19th-century India, several regions experienced de-urbanization due to the impact of British colonial policies and economic shifts.
Machlipatnam, located in Andhra Pradesh, was a significant port city during the 17th and 18th centuries. However, it began to decline in the 19th century due to the decline of the textile industry and the shift in trade routes. The British East India Company's control over trade and the decline of the local textile industry led to a significant reduction in the city's economic activities, resulting in de-urbanization.
Surat, located in Gujarat, was another important port city that experienced de-urbanization in the 19th century. The city's decline was primarily due to the shift in trade patterns and the decline of the textile industry. The British East India Company's control over trade and the establishment of other ports like Bombay led to a decline in Surat's economic importance, resulting in de-urbanization.
Seringapatam, now known as Srirangapatna, was the capital of the Kingdom of Mysore. The city experienced de-urbanization after the fall of the Kingdom of Mysore and the subsequent British occupation. The British annexation of the region and the decline of the local economy led to a significant reduction in the city's urban characteristics.
On the other hand, Bombay, now known as Mumbai, did not de-urbanize in the 19th century. Instead, it continued to grow and develop as a major port city under British rule. The city's strategic location and the British East India Company's focus on developing Bombay as a major port led to significant urbanization and economic growth. The city became a hub for trade, commerce, and industry, and its population and urban characteristics continued to expand throughout the 19th century.
Therefore, the correct answer is that Bombay was the region that did not de-urbanize in the 19th century. This question tests the understanding of urbanization trends and the historical context of British colonial rule in India during the 19th century.
