Explanation

To determine the correct order of the geological eras based on the evolutionary timeline of Earth, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Geological Eras**:
- The Earth has undergone significant changes over millions of years, which are categorized into different geological eras.

2. **Identify the Eras**:
- The main geological eras are:
- **Archeozoic Era**: This is the earliest era when the Earth was forming and the first simple life forms appeared.
- **Proterozoic Era**: This era is characterized by the appearance of oxygen in the atmosphere and the development of simple multicellular organisms.
- **Paleozoic Era**: Known as the era of ancient life, it saw significant changes and the emergence of complex life forms.
- **Mesozoic Era**: Often referred to as the age of reptiles, this era included the time of dinosaurs.
- **Cenozoic Era**: This is the current era, known as the age of mammals and birds.

3. **Chronological Order**:
- The correct chronological order of these eras based on their occurrence is:
1. **Archeozoic Era**
2. **Proterozoic Era**
3. **Paleozoic Era**
4. **Mesozoic Era**
5. **Cenozoic Era**

4. **Evaluate the Options**:
- Given the options, we need to identify the one that matches the chronological order we established.

5. **Select the Correct Answer**:
- The correct order based on the analysis is:
- **Archeozoic, Proterozoic, Paleozoic, Mesozoic, Cenozoic**.

### Final Answer:
The correct order of the geological eras is: **Archeozoic, Proterozoic, Paleozoic, Mesozoic, Cenozoic**.
