Explanation: Sikkim is a small state located in the northeastern part of India, known for its rich biodiversity and cultural heritage. Understanding the geographical location of Sikkim is essential for comprehending its political and cultural dynamics. Sikkim is bordered by three countries and one Indian state:
1. **Nepal to the West**: Nepal shares a border with Sikkim to the west. This border is significant because it is a major route for trade and cultural exchange between the two regions.
2. **Bhutan to the East**: Bhutan is the correct answer for the eastern border of Sikkim. This border is crucial for understanding the geopolitical relationship between Sikkim and Bhutan, as well as the broader context of the northeastern region of India.
3. **Tibet (China) to the North**: Tibet, which is part of China, borders Sikkim to the north. This border is significant due to the complex political relationship between India and China, and the strategic importance of the region.
4. **West Bengal (India) to the South**: The southern part of Sikkim borders the Indian state of West Bengal. This border is important for internal trade and cultural connections within India.
The geographical layout of Sikkim is such that it is surrounded by these four entities, making it a landlocked state. The eastern border with Bhutan is particularly important because it represents a significant part of Sikkim's international border and plays a role in the state's economic and cultural interactions with its neighbors.

It is important to remember the specific directions of the borders to avoid confusion with other neighboring states and countries.
