Solution.

Answer: (c) 2 and 3

  1. Statement 1 is correct: Uttar Pradesh shares its boundary with eight Indian States (Uttarakhand, Himachal Pradesh, Haryana, Rajasthan, Madhya Pradesh, Chhattisgarh, Jharkhand, and Bihar) plus Delhi, the highest among all Indian States.
  2. Statement 2 is incorrect: West Bengal shares the longest international border among all Indian States (around 2,217 km with Bangladesh alone, plus Nepal and Bhutan), exceeding Rajasthan's border with Pakistan (around 1,070 km).
  3. Statement 3 is incorrect: Sikkim is not the only State bordering just one other Indian State; Meghalaya also shares its domestic boundary with only one Indian State (Assam).
