Which of the following British administrators and explorers played a pioneering role in mapping the Mishmi and Abor hills of the northeastern frontier during the late 19th century?

💡 Solution & Explanation

Explorers and political officers such as T.T. Cooper and Captain F.W. Trench undertook hazardous expeditions into the interior hills of present-day Arunachal Pradesh during the British colonial era to assess trade routes, survey topography, and establish political contact with indigenous clans. Ney Elias explored parts of western China and the Himalayan frontiers, but Cooper's journeys specifically focused on the Brahmaputra-Yangtze river links through the Mishmi hills. These explorations provided the empirical groundwork for subsequent colonial frontier demarcation.
