Explanation: Chhattisgarh is a state located in central India, and its geographical position is crucial for understanding its neighboring states. The state of Chhattisgarh is bordered by several other states, each contributing to its unique geographical layout.
Chhattisgarh shares its borders with the following states:
- **Madhya Pradesh**: This state borders Chhattisgarh to the west and south. The border between these two states is extensive and includes several districts of Chhattisgarh.
- **Odisha**: This state borders Chhattisgarh to the east and southeast. The border between these two states is significant, particularly in the eastern and southeastern regions of Chhattisgarh.
- **Uttar Pradesh**: This state borders Chhattisgarh to the north and northwest. The border between these two states is significant, as it includes parts of the northern and western regions of Chhattisgarh.
Bihar, on the other hand, does not share a border with Chhattisgarh. Bihar is located to the northeast of Chhattisgarh and is separated by Uttar Pradesh and Madhya Pradesh. This geographical separation means that Bihar is not a direct neighbor of Chhattisgarh.
Understanding the geographical layout of Chhattisgarh and its neighboring states is essential for identifying which state does not share a border with it. The correct answer is Bihar, as it is the only state among the options that does not share a border with Chhattisgarh.
This concept is important for students preparing for competitive examinations such as the UPSC, SSC, and state PSCs, where questions on state geography and borders are common. It is also useful for students studying the geography of central India and the layout of its states.
