  1. AAbout one-third of the area of the country records more than 750 millimetres of annual rainfallCorrect
  2. BThe dominant source of irrigation in the country is wells
  3. CAlluvial soil is the predominant type of soil in the northern plans of the country
  4. DThe mountain areas accounts for about thirty percent of the surface area of the country

Explanation

The statement A is correct because a major portion of India receives significant precipitation due to the southwest monsoon. In reality, much more than one third of the country actually receives over 750 millimetres of annual rainfall. Statistics show that nearly 75 percent of Indias total land area receives rainfall exceeding this threshold. Therefore, the statement that about one third records more than 750 millimetres is a statistically valid, though conservative, representation of the countrys climatic profile. Regarding other options, tube wells and wells combined are the dominant irrigation source, alluvial soil covers about 40 percent of total land but is specific to the plains, and mountains account for roughly 10.7 percent of the surface area.
