To determine which kingdom has the maximum members from the given list (Rhizobium, Azolla, Ascobolus, Golden Algae, Euglena, Frankia, Nostoc, Anthoceros, Oscillatoria, Rumenococcus), we can categorize each organism based on their biological classification.
### Step-by-Step Solution:
1. **Identify Each Organism's Classification**:
- **Rhizobium**: This is a bacterium, which belongs to the kingdom **Monera**.
- **Azolla**: This is a water fern, which belongs to the kingdom **Plantae**.
- **Ascobolus**: This is a type of fungus, which belongs to the kingdom **Fungi**.
- **Golden Algae**: This is a type of algae, which belongs to the kingdom **Protista**.
- **Euglena**: This is a protist that has characteristics of both plants and animals, also belonging to the kingdom **Protista**.
- **Frankia**: This is a bacterium, which belongs to the kingdom **Monera**.
- **Nostoc**: This is a cyanobacterium (blue-green algae), which belongs to the kingdom **Monera**.
- **Anthoceros**: This is a hornwort, which belongs to the kingdom **Plantae**.
- **Oscillatoria**: This is another cyanobacterium, which belongs to the kingdom **Monera**.
- **Rumenococcus**: This is a bacterium, which belongs to the kingdom **Monera**.
2. **Count the Members in Each Kingdom**:
- **Monera**: Rhizobium, Frankia, Nostoc, Oscillatoria, Rumenococcus (Total: 5 members)
- **Plantae**: Azolla, Anthoceros (Total: 2 members)
- **Fungi**: Ascobolus (Total: 1 member)
- **Protista**: Golden Algae, Euglena (Total: 2 members)
3. **Determine the Kingdom with Maximum Members**:
- From the counts, we see that the kingdom with the maximum members is **Monera** with 5 members.
### Conclusion:
The kingdom with the maximum members from the provided list is **Monera**.
