Indian States Geography and Boundaries

Statements 2 and 3 are incorrect and form the required answer. West Bengal shares the longest international land border segment among all Indian states (~2,217 km along Bangladesh), whereas Rajasthan's border along Pakistan is shorter. Statement 3 is incorrect because Meghalaya also shares its domestic border with only one Indian state (Assam), matching Sikkim's profile (which borders only West Bengal). Statement 1 is a correct geographical fact, as Uttar Pradesh borders eight separate states and one Union Territory.
