In which one of the following States are Namchik-Namphuk Coalfields located?

The Namchik–Namphuk coalfields are located in Arunachal Pradesh. A standard geography text explicitly lists “Namchik – Namphuk (Arunachal Pradesh)” among tertiary coal occurrences in the northeastern states, identifying the block as part of Arunachal Pradesh’s coal resources [1]. This location is corroborated by official government communications and press releases concerning the Namchik‑Namphuk coal block, which discuss the block’s reserves, allocation history, and the inauguration of commercial mining in Changlang district of Arunachal Pradesh [2]. Given these authoritative references, the correct choice from the options provided is Arunachal Pradesh.
