- A.Clean Coal for a Green Future
- B.NextGen AI for Smart Mining
- C.Digital Mines, Safer Miners
- D.Mission Zero Overburden
Correct answer
Explanation
The correct answer is NextGen AI for Smart Mining. Winners and runners-up of the hackathon held on this theme were honoured at the same ceremony at Raipur, and their entries applied artificial intelligence to problems of operational efficiency, mine safety and environmental sustainability in the coal sector. The winning entries came from CSIR-NEERI at Nagpur, a Ranchi firm working with IIT (ISM) Dhanbad, CSIR-CLRI at Chennai with a Kolkata partner, and a consortium around CSIR-CMERI at Durgapur together with C-DAC Thiruvananthapuram. The other three options are invented themes of the kind an examiner would place beside the real one. Candidates should link the theme to the institutions named, since questions often ask which research laboratory figured among the winners rather than asking for the theme itself.
