Explanation: The textile industry in Rajasthan has a rich history, with the establishment of the first mill, the Krishna Mill, marking a significant milestone in the state's industrial development. This mill was set up in Ajmer, which became a center for textile production in Rajasthan.
Ajmer, located in the western part of Rajasthan, has historically been an important city due to its strategic location and cultural significance. The establishment of the Krishna Mill in Ajmer in the early 20th century was a crucial step in the industrialization of the region. The mill played a vital role in the economic development of the city and the state, providing employment and contributing to the growth of the textile industry.
The textile industry in Rajasthan has evolved over the years, with various districts contributing to its growth. However, the establishment of the Krishna Mill in Ajmer remains a significant event in the state's industrial history. It symbolizes the beginning of a new era of industrialization and economic development in Rajasthan.
It is important to note that while other districts like Chittorgarh, Bhilwara, and Jaipur have also played significant roles in the textile industry, they were not the sites of the first mill. Chittorgarh is known for its historical and cultural importance, Bhilwara for its woolen and textile industries, and Jaipur for its diverse industrial activities. However, the specific historical fact that the Krishna Mill was established in Ajmer is crucial for understanding the industrial development of Rajasthan.
In summary, the correct answer is Ajmer because it is the district where the first mill, the Krishna Mill, was established, marking a significant moment in the industrial history of Rajasthan. This fact highlights the importance of Ajmer in the context of the state's industrial development and the growth of the textile industry.
