Option 2: developing genetically modified crop plants

Detailed Solution

Explanation:

Bollgard I Bt cotton (single-gene technology) is India’s first biotech crop technology approved for commercialization in India in 2002. It was followed by Bollgard II – double-gene technology in mid-2006 by the Genetic Engineering Approval Committee (GEAC), the Indian regulatory body for biotech crops.
