In the context of agricultural statistics, statement 1 is correct, as India does have a larger arable area than China. However, statement 2 is incorrect; China has a higher proportion of irrigated area compared to India due to its advanced irrigation infrastructure. Statement 3 is also incorrect, as China's average agricultural productivity per hectare generally exceeds that of India, largely due to better technology, practices, and inputs. Therefore, only one statement is accurate. Understanding these dynamics is crucial for the UPSC Prelims, as they reflect the complexities of agricultural development, food security, and resource management in two major economies.
