Correct answer: (c) Dr. Harsh Vardhan
Explanation
- A
Ravishankar Prasad
Ravi Shankar Prasad handled law and electronics-IT portfolios, not the July 2018 SAFAR inauguration keyed here. This option is not the key.
- B
Piyush Goyal
Piyush Goyal has held power, coal and railways; he is not the minister named for this SAFAR launch. This option is therefore wrong.
- C
Dr. Harsh Vardhan
Dr Harsh Vardhan, then Union Minister for Science and Technology and Earth Sciences, inaugurated SAFAR-related air-quality and weather-forecast facilities in July 2018. SAFAR is an IMD–IITM system. This option is the official key.
- D
None of the above
A named minister did inaugurate it, so none of the above is incorrect. This option is not the key.
Summary. Official key is (c) Dr. Harsh Vardhan. SAFAR, the System of Air Quality and Weather Forecasting and Research, is run with the Indian Institute of Tropical Meteorology and the India Meteorological Department. The July 2018 inauguration is paired with the then Earth Sciences minister. Prasad and Goyal had other ministries. Only (c) matches.
