The correct option is D Raichur
Hutti gold mine is located in the Raichur district of Karnataka. In the Hutti gold field the gold mining belt is 3.7 km long and 1,220 m wide with six auriferous quartz reefs. It produced 593.3 kg of gold in 1915, but the production fell and the mine had to be closed down in 1920. The main problem with the Hutti mines is the low grade of ore.
