Solution
The correct option is B 1980
Isolation of Bt gene from bacterium (Bacillus thuringiensis) was taken up in 1980. Bt cotton is a pest-resistant genetically modified organism (GMO) cotton variety, which produces an insecticide to bollworm. It is produced by Monsanto. The gene coding for Bt toxin has been inserted into cotton as a transgene, causing it to produce this natural insecticide in its tissues. In many regions, the main pests in commercial cotton are lepidopteran larvae, which are killed by the Bt protein in the genetically modified cotton they eat. This eliminates the need to use large amounts of broad-spectrum insecticides to kill insects.
