Q. If you travel by road from Kohima to Kottayam, what is the minimum number of States within India through which you can travel, including the origin and the destination? (UPSC Prelims 2017)
Answer: 7
Notes: The correct answer is [B] 7. This question tests your knowledge of India's political geography and the most efficient road routes across the country.To find the minimum number of states, you must navigate from Nagaland (Northeast) to Kerala (South) while passing through the fewest borders possible.The Optimal Route:

1. Nagaland (Origin): Kohima is the capital.
2. Assam: To leave the Northeast, you must pass through Assam.
3. West Bengal: To enter mainland India from the Northeast, you must cross the "Chicken's Neck" (Siliguri Corridor) in West Bengal.
4. Odisha: Traveling south along the eastern coast.
5. Andhra Pradesh: Continuing down the eastern coast.
6. Tamil Nadu: Entering from the north/northwest of the state to reach the border of Kerala.
7. Kerala (Destination): Kottayam is located here.

Why other counts are incorrect:

• Avoiding Telangana/Karnataka: While you can go through Telangana or Karnataka, doing so usually maintains the count at 7 or increases it to 8, depending on the specific highway. The coastal route (NH 16) through Odisha and Andhra Pradesh is the most direct "minimum state" corridor.
• The "Seven" breakdown:
  • Nagaland → Assam → West Bengal → Odisha→ Andhra Pradesh → Tamil Nadu → Kerala.
