Explanation: NEFA, or the North-East Frontier Agency, was an administrative area in India that was established in 1954. It comprised territories along the Sino-Indian border and tribal areas north of Assam. The establishment of NEFA was a significant administrative move by the Indian government to consolidate control over a strategically important region.
The Sino-Indian border is the international boundary between India and China, and it is a region of considerable geopolitical importance. The area around NEFA has been a subject of territorial disputes between India and China, with both countries claiming parts of the region. The establishment of NEFA was a response to these geopolitical tensions and aimed to strengthen India's administrative control over the region.
The tribal areas north of Assam were also included in NEFA. These areas were inhabited by various indigenous tribes, and the inclusion of these regions in NEFA was intended to provide a unified administrative structure for these diverse communities. The tribal areas were significant not only for their cultural and social importance but also for their strategic location along the Sino-Indian border.
Understanding the historical context of NEFA is crucial for comprehending the territorial disputes and administrative changes in the region. NEFA was later renamed Arunachal Pradesh in 1987, becoming a full-fledged state of India. The renaming and statehood of Arunachal Pradesh were part of a broader process of administrative and political consolidation in the northeastern part of India.
In summary, the correct answer is (A) Sino-Indian, as NEFA was established in 1954 and comprised territories along the Sino-Indian border and tribal areas north of Assam. This region was strategically important for both India and China, and the establishment of NEFA was a significant administrative move by the Indian government to consolidate control over this area.
