For which of the following minerals are Singhbhum and Hazaribagh of Bihar famous?
A
Copper
B
Coal
C
Bauxite
D
Gold
Correct Option:
A
Explanation
The older wording says "Bihar" because Singhbhum and Hazaribagh later became part of Jharkhand. Historically, the Singhbhum-Hazaribagh belt is associated with copper deposits and ancient copper workings, so copper is the stronger factual answer despite some unofficial keys giving coal.
