Main objective of production of herbicide resistant GM crops is to

Options

A. encourage eco-friendly herbicides
B. reduce herbicide accumulation in food products for health safety
C. eliminate weeds from the field without the use of manual labour
D. eliminate weeds from the field without the use of herbicides

Explanation

### Step-by-Step Text Solution:

1. **Understanding the Problem**: The main issue faced by farmers is the competition between crops and weeds for nutrients in the soil. Weeds grow rapidly and can significantly reduce crop yield and quality.

2. **Use of Herbicides**: To combat the problem of weeds, farmers have traditionally used herbicides, which are chemicals designed to kill or inhibit the growth of unwanted plants. Glyphosate is one such herbicide that has been widely used.

3. **Health Concerns**: The use of herbicides raises health concerns as residues can remain in food products, potentially affecting human health when consumed.

4. **Genetic Modification**: To address these issues, scientists have developed genetically modified (GM) crops that are resistant to specific herbicides. This means that these crops can survive the application of herbicides that would normally kill them.

5. **Main Objective**: The primary goal of producing herbicide-resistant GM crops is to allow farmers to eliminate weeds effectively without harming the crops. This leads to reduced reliance on manual labor for weeding and minimizes the accumulation of herbicides in food products, thus enhancing health safety.

6. **Examples of GM Crops**: Crops such as maize and cotton have been genetically modified to be herbicide-resistant, allowing for more efficient farming practices.
