Main objective of production/use of herbicide resistant GM crops is to
A - Reduce herbicide accumulation in food articles for health safety.
B - Eliminate weeds in the field without the use of herbicides
C - Eliminate weeds from the field without the use of manual labour.
D - Soil pollution and biomagnification caused by herbicides.
Which of the following statements are correct?

Options

A. A only
B. B only
C. A,B,C and D
D. C only

Answer

To determine the main objective of the production and use of herbicide-resistant genetically modified (GM) crops, let's analyze each option provided in the question.

### Step-by-step Solution:

1. **Understanding Herbicide Resistance**:
- Herbicide-resistant GM crops are genetically modified to withstand certain herbicides that would normally kill them. This allows farmers to apply herbicides to control weeds without harming the crops.

2. **Evaluating Option A**:
- **Statement**: "Reduce herbicide accumulation in food articles for health safety."
- **Analysis**: This statement is partially true. While herbicide-resistant crops can potentially lead to lower herbicide residues in food, the primary goal is not necessarily to reduce accumulation for health safety but to allow effective weed control.

3. **Evaluating Option B**:
- **Statement**: "Eliminate weeds in the field without the use of herbicides."
- **Analysis**: This statement is incorrect. Herbicide-resistant crops do not eliminate the need for herbicides; rather, they allow the use of herbicides without damaging the crops.

4. **Evaluating Option C**:
- **Statement**: "Eliminate weeds from the field without the use of manual labour."
- **Analysis**: This statement is correct. By using herbicide-resistant crops, farmers can manage weeds more efficiently, reducing the need for manual labor to remove them.

5. **Evaluating Option D**:
- **Statement**: "Soil pollution and biomagnification caused by herbicides."
- **Analysis**: This statement is somewhat true. The use of herbicide-resistant crops can potentially reduce soil pollution and biomagnification by allowing for more targeted herbicide application, but it does not eliminate these issues entirely.

6. **Conclusion**:
- After analyzing all options, we find that options A, C, and D have elements of truth, while option B is incorrect. Therefore, the main objective of herbicide-resistant GM crops is to manage weeds effectively, which can lead to reduced manual labor and potentially lower herbicide residues in food.

### Final Answer:
The correct statements regarding the main objective of herbicide-resistant GM crops are A, C, and D.
