Correct answer
Explanation
Kolar Gold Fields (KGF) in Karnataka is India's richest, deepest (over 3 km), and oldest gold mine, operating for over 120 years. It produced significant gold quantities until its closure in 2001. Golconda is famous for diamonds, not gold. Nellore is not known for gold mining. KGF remains legendary in India's mining history.
