aIt is genetically modified dwarf variety which is resistant to drought
bIt is a genetically modified variety which is pest resistant
cIt is a genetically modified variety with ten times higher protein content than regular maize crop
dIt is a genetically modified variety used exclusively for bio-fuel production
✓ Correct answer: b) It is a genetically modified variety which is pest resistant
ExplanationMon 863 maize was genetically modified to produce a protein called Cry3Bb1 derived from the soil bacterium Bacillus thuringiensis (Bt).This protein is toxic to the corn rootworm which is a major pest that damages maize crops.By incorporating this trait, Mon 863 reduces the need for chemical pesticides and improves crop yields.374
