Explanations:The seven sisters states of India are a group of seven contiguous states located in the northeastern part of the country. These states are Arunachal Pradesh, Assam, Manipur, Meghalaya, Mizoram, Nagaland, and Tripura. The term "seven sisters" is used to describe these states due to their geographical proximity and shared cultural heritage. Each of these states has a unique history and cultural identity, but they are collectively referred to as the seven sisters due to their geographical and political significance.
Understanding the geographical location and political status of each state is crucial for identifying which states belong to the seven sisters. Arunachal Pradesh, Assam, Manipur, Meghalaya, Mizoram, Nagaland, and Tripura are all located in the northeastern region of India and share a common border with each other, forming a contiguous block. This geographical and political proximity is what defines them as the seven sisters.
Sikkim, on the other hand, is a state located in the northeastern Himalayan region but is not part of the group of seven contiguous states. Sikkim is situated between Nepal, Bhutan, and Tibet, and it was admitted as the 22nd state of India in 1975. While Sikkim is geographically close to the seven sisters, it is not considered one of them due to its distinct political and geographical status.
Therefore, when asked which state is NOT a part of the seven sisters states of India, the correct answer is Sikkim. This question tests the student's knowledge of the geographical and political boundaries of the northeastern states of India and their ability to distinguish between the seven sisters and other states in the region.
