Concept:The surname 'Chuhad' is historically linked to the Bhumij tribe, known for their revolt against British land revenue policies.
Explanation:The Bhumij are a Munda tribal group from West Bengal, Odisha, and Jharkhand.
The surname 'Chuhad' is specifically associated with this tribe.
In 1832-33, the Bhumij rose in revolt under leader Ganga Narayan, an event known locally as "Ganga Narayan ka Hangama".
The other tribes given as options are different: Birhor (forest people, nomadic), Sauria Pahadia (Dravidian, Rajmahal Hills), and Asura (iron smelters, PVTG in Jharkhand).
None of them share the surname 'Chuhad'.
Hence, the correct match is the Bhumij tribe.
Answer:B. Bhumij
