Which of the following is an agricultural application of genetic engineering?

• A. Temperature resistance
• B. Herbicide resistance
• C. Fertilizer resistance
• D. Soil acidity tolerance

Answer: (B)

Herbicide resistance is a significant agricultural application of genetic engineering because it allows crops to survive applications of herbicides that would typically kill them. This advancement enables farmers to control weeds effectively without harming their crops, resulting in better yields and reduced competition for resources. Genetic engineering techniques can introduce specific traits into plants, such as the ability to metabolize certain herbicides, allowing for more effective weed management strategies.

Temperature resistance and soil acidity tolerance are also important traits in agriculture; however, they might not be as directly associated with common genetic engineering practices like the development of herbicide-resistant crops. Fertilizer resistance doesn't commonly occur as a trait because crops generally do not resist fertilizers but rather can benefit from them when properly applied.

Overall, herbicide resistance stands out as a primary focus of genetic engineering in agriculture, providing a practical solution to weed management while promoting more sustainable farming practices.
