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?

Confirms the existence and identity of 'Itanagar' as the capital of Arunachal Pradesh, giving a concrete target for any toponymic origin inquiry.

A student can locate Ita Fort on a map relative to Itanagar and check historical references for naming links.

Gives a clear example (Golkonda → Muhammad Nagar) where a fort/place was renamed or the settlement name changed around a fort, illustrating the common pattern of settlements being named after forts or their builders.

Apply this pattern: check whether local histories record a fort influencing the later town name 'Itanagar' or an older settlement named 'Ita'.

Shows another explicit example (Fort William → seat of Calcutta) where a fortified settlement's name became the place-name and administrative centre, reinforcing that forts often give names to urban centres.

Use this pattern to hypothesize that Itanagar could similarly derive from a fort named 'Ita' and then search historical records or maps for such a sequence.

Describes prominent forts (Kumbhalgarh) as central strongholds associated with regional identity, implying forts frequently serve as naming anchors for regions or towns.

A student could check whether Ita Fort was a prominent local stronghold whose name could plausibly transfer to the adjacent settlement now called Itanagar.

Notes that place and administrative names have been changed or renamed historically (states/islands), indicating that names can shift and may derive from historical features or constructions.

Use this to motivate checking historical administrative records or gazetteers for any official renaming that tied Itanagar's name to Ita Fort.
