Explanations:The question involves understanding the geographical and administrative details of the South Asian region and the status of Andaman and Nicobar Islands within India. The South Asian region is a well-defined geographical area that includes several countries. The countries in South Asia are India, Pakistan, Bangladesh, Sri Lanka, Nepal, Bhutan, and Maldives. This list is based on the geographical and political boundaries of the region.
Statement 1 lists the countries in South Asia as India, Pakistan, Bangladesh, Sri Lanka, Nepal, and Bhutan. This statement is true, but it omits Maldives, which is also a part of South Asia. However, the omission of Maldives does not make the statement false, as it still correctly identifies the other countries in the region.
Statement 2 claims that Andaman and Nicobar Islands are a part of West Bengal. This statement is false. Andaman and Nicobar Islands are a union territory of India, not a part of any state. They are located in the Bay of Bengal and are an integral part of the Indian Union, governed directly by the Union Government.
Statement 3 lists the countries in South Asia as India, Pakistan, Bangladesh, Sri Lanka, Maldives, Nepal, and Bhutan. This statement is true and correctly includes all the countries in the South Asian region.
Therefore, the correct answer is option D, which states that only statements 1 and 3 are true. Statement 1 is true because it correctly identifies the majority of the countries in South Asia, and statement 3 is true because it correctly lists all the countries in South Asia, including Maldives.
