Explanations:The question pertains to the location where Santosh joined his college, which is a piece of general knowledge related to the state of Rajasthan. Rajasthan is a state in India known for its rich cultural heritage, historical sites, and significant educational institutions. The capital city of Rajasthan is Jaipur, which is also a major educational hub in the state.
Jaipur is home to several prestigious colleges and universities, making it a popular choice for students seeking higher education. The city's educational institutions are well-regarded and offer a wide range of courses and programs. Given this context, it is reasonable to conclude that Santosh, as a notable figure in Rajasthan, would have joined his college in Jaipur.
Delhi, while a major city and the capital of India, is not the location of Santosh's college. It is important to distinguish between the capital of India and the capital of Rajasthan when answering questions about specific locations within the state. The confusion might arise from the prominence of Delhi as a national capital, but in the context of Rajasthan's general knowledge, Jaipur is the correct answer.
Therefore, the correct answer is that Santosh joined the college in Jaipur. This aligns with the educational landscape of Rajasthan and the significance of Jaipur as a major educational center within the state.
