Arunachal Pradesh's capital is indeed Itanagar, making this the correct pair. However, option B contains a quality issue - 'Gujrat' is misspelled (should be 'Gujarat'). Option C is incorrect because Manipur's capital is Imphal, not Aizwal (which is Mizoram's capital). Option D is wrong because Pondicherry's capital is Pondicherry itself, while Port Blair is the capital of Andaman and Nicobar Islands.
