Main objective of production/use of herbicide resistant GM crops is to

Options

A. eliminate weeds from the field without the use of manual labour
B. Eliminate weeds from the field without the use of herbicides
C. Encourage eco-friendly herbicides
D. Reduce herbicide accumulation in food articles for health safety

Answer

**Step-by-Step Solution:**

1. **Understanding the Question**: The question asks about the main objective of producing and using herbicide-resistant genetically modified (GM) crops.

2. **Analyzing the Options**: We need to evaluate each option provided:
- **Option A**: Eliminate weeds from the field without the use of manual labor.
- **Option B**: Eliminate weeds from the field without the use of herbicides.
- **Option C**: Increase eco-friendly herbicides.
- **Option D**: Reduce herbicide accumulation in food articles for health safety.

3. **Evaluating Option A**: This option suggests that herbicide-resistant GM crops allow farmers to control weeds effectively without needing to manually remove them. This is a significant advantage as it saves time and labor costs.

4. **Evaluating Option B**: This option implies that herbicide-resistant crops can eliminate weeds without using any herbicides at all. This is incorrect because the purpose of these crops is to withstand herbicides, not to eliminate their use entirely.

5. **Evaluating Option C**: This option suggests that the objective is to increase the use of eco-friendly herbicides. While this may be a benefit, it is not the primary objective of herbicide-resistant GM crops.

6. **Evaluating Option D**: This option suggests that the main concern is to reduce herbicide accumulation in food articles for health safety. While this is an important consideration, it is not the main objective of developing herbicide-resistant crops.

7. **Conclusion**: After evaluating all the options, the correct answer is **Option A**: Eliminate weeds from the field without the use of manual labor. This reflects the primary goal of developing herbicide-resistant GM crops, which is to facilitate easier weed management.
