Answer- B
The Indian government has recently introduced a mobile application called "KhananPrahari" and a web application called Coal Mine Surveillance and Management System (CMSMS) to combat illegal coal mining.
These applications will enable the reporting of unauthorized mining activities, and the relevant law enforcement authorities can take prompt and appropriate action against them.
The CMSMS has been created as an e-Governance initiative of the Government of India to use space technology for curbing illegal mining and ensuring transparency in the action taken against it.
