Introduction of genetically modified food is not desirable because

Options

A. It will affect economy of developing countries
B. The products are less tasty
C. They are costly
D. There is danger of entry of toxins and virus in food

Answer

### Step-by-Step Solution:

1. **Understanding Genetically Modified Foods (GMOs)**:
- Genetically modified foods are derived from organisms whose genetic material (DNA) has been altered in a way that does not occur naturally. This modification is done to enhance certain traits such as resistance to pests, improved nutritional content, or longer shelf life.

2. **Concerns Regarding GMOs**:
- There are several concerns associated with the introduction of genetically modified foods. These include potential economic impacts, taste preferences, cost implications, and health risks.

3. **Economic Impact**:
- One argument against GMOs is that they may negatively affect the economy of developing countries. However, this is not universally accepted as the primary concern.

4. **Taste and Cost**:
- Some people believe that genetically modified foods are less tasty compared to natural foods. Additionally, there is a perception that GMOs are more expensive than their non-GMO counterparts, but this is not a definitive reason against their introduction.

5. **Health Risks**:
- A significant concern regarding GMOs is the potential danger of toxins and viruses entering the food supply. This risk arises from the genetic modifications that may inadvertently introduce harmful substances or pathogens into the food chain.

6. **Conclusion**:
- Among the various concerns, the most pressing issue is the potential health risk associated with the entry of toxins and viruses into food due to genetic modifications. Therefore, the introduction of genetically modified foods is considered undesirable primarily because of this health risk.

### Final Answer:
The introduction of genetically modified food is not desirable primarily because there is a danger of entry of toxins and viruses in food.
