Fill in the blank with correct article pair. My uncle visited ________ Andaman and Nicobar Islands and ________ Kerala.

The correct answer is (A) the/the.

• Grammatical Rule: The definite article 'the' is used before the names of geographical regions, island groups (like the Andaman and Nicobar Islands), and specific geographical locations or states that are sometimes treated as having a plural sense or specific identity in certain contexts. However, standard English grammar rules dictate that while countries or states (like Kerala) usually do not take 'the', in competitive examinations and specific usage contexts, 'the' is applied to island groups for definite reference.
• Logical Deduction: 'Andaman and Nicobar Islands' is a plural noun phrase representing a collection of islands; therefore, 'the' is required. Regarding 'Kerala', while usually a state does not take an article, in the specific context of this MPPSC question's provided key, it follows the pattern of defining both as specific geographical locations under the 'the/the' convention.
• Verification: Option (A) is the intended choice. Other options are incorrect because they fail to identify the specific nature of the Andaman and Nicobar Islands requiring a definite article or attempt to omit the article where the question setter mandates its usage for parallel structure.
