When did Chhotanagpur Tribal Revolt occur?

BPSC treated this question as having no correct option (cancelled).

Explanation

No revolt took place specifically known as the “Chotanagpur tribal revolt.” However, there was a long series of revolts in this region, known by different names. None of the given dates matches the correct period of any revolt. Major revolts of this region include the Kol Revolt (1831–32), Santhal Revolt (1855–56), and Munda Revolt (1899–1900). Therefore, none of the options is correct.
