Explanation: To understand the context of the statements provided, it is essential to delve into the geography, economy, and historical aspects of Rajasthan.
1. **City Based Performance**: This concept refers to the performance of various branches or sectors based on their location within a city or urban area. However, it is not universally applicable to all branches in Rajasthan. The performance of branches can vary based on factors such as infrastructure, market demand, and local economic conditions. Therefore, the first statement is incorrect.
2. **Indus Valley Civilization Sites**: The Indus Valley Civilization, also known as the Harappan Civilization, was one of the world's earliest urban civilizations. It flourished in the northwestern regions of the Indian subcontinent, primarily in present-day Pakistan and parts of northwestern India. Rajasthan, being located in the western part of India, does not have any known Indus Valley Civilization sites. The second statement is correct.
3. **Cotton Cultivation**: Rajasthan is known for its agricultural practices, and cotton is one of the major crops cultivated in the state. The arid and semi-arid climate of Rajasthan, along with the availability of irrigation facilities, makes it suitable for cotton cultivation. The third statement is correct.
In summary, the correct answer is (D) Only 2, 3. The second and third statements are true, while the first statement is incorrect. Understanding the geography, economy, and historical context of Rajasthan is crucial to correctly identifying the true statements. This knowledge is essential for students preparing for examinations related to Rajasthan's geography and economy, such as Rajasthan State Examinations, UPSC Prelims, and State PSC Exams.
