Answer

**Step-by-Step Text Solution:**

1. **Understanding the Question**: The question asks for structures that are specifically built to protect grains from pests and microbes.

2. **Identifying the Options**: The options mentioned in the video include silos, godowns, sacks, and metallic bins.

3. **Analyzing Each Option**:
- **Silos**: These are large cylindrical tanks designed to store grains. They are built to prevent moisture and pests from affecting the stored grains.
- **Godowns**: These are large storage areas where silos may be kept. They are used for storing crops before marketing but do not specifically protect against pests and microbes.
- **Sacks**: These are bags used for storing grains. However, they are not effective in preventing pest and microbial attacks as they can be easily penetrated.
- **Metallic Bins**: While they are used for storage, they can react with certain grains, making them less ideal for long-term storage.

4. **Conclusion**: The best option that specifically protects grains from pests and microbes is **silos**.

**Final Answer**: Silos are specially built structures that protect grains from pests and microbes.
