The correct Answer is:
### Step-by-Step Solution: 1. **Understanding Aflatoxins**: Aflatoxins are a group of toxic compounds produced by certain molds (fungi) that can contaminate food products, particularly grains. They are known to be carcinogenic and pose serious health risks. 2. **Identifying the Source**: The primary fungi responsible for the production of aflatoxins are *Aspergillus flavus* and *Aspergillus parasiticus*. These fungi thrive in warm and humid environments, which are conducive to their growth. 3. **Recognizing the Conditions**: Storage grains, such as maize, can become contaminated with these fungi when stored in conditions that are warm and humid, leading to the production of aflatoxins. 4. **Eliminating Incorrect Options**: - Other organisms like bacteria and viruses do not produce aflatoxins. - Yeasts, while they are fungi, do not produce aflatoxins either. Therefore, they are not responsible for the contamination of storage grains with aflatoxins. 5. **Conclusion**: The correct answer to the question is *Aspergillus flavus*, as it is the main fungus responsible for the production of aflatoxins in storage grains. ### Final Answer: Storage grains come to have aflatoxin due to the growth of *Aspergillus flavus*. ---
