Consider the following pairs: State — Description. I. Arunachal Pradesh : The capital is named after a fort, and the State has two National Parks. II. Nagaland : The State came into existence on the basis of a Constitutional Amendment Act. III. Tripura : Initially a Part 'C' State, it became a centrally administered territory with the reorganization of States in 1956 and later attained the status of a full-fledged State. How many of the above pairs are correctly matched?

I. Arunachal Pradesh — Itanagar is named after Ita Fort, and Arunachal Pradesh has two National Parks: Namdapha and Mouling. Verdict: Correct.

II. Nagaland — This was my earlier error. Nagaland was created by the State of Nagaland Act, 1962 under Article 3, not on the basis of a Constitutional Amendment Act. The 13th Constitutional Amendment only inserted Article 371A (special provisions). Verdict: Incorrect.

III. Tripura — Tripura was initially a Part C State, became a Union Territory in 1956, and later attained full statehood in 1972. Verdict: Correct.

Hence, only two pairs are correctly matched.
