Solution

The answer is the fourth one: 4.5 billion years.

Explanation for each option:

5020 years: This is incorrect. This age is far too young and does not align with scientific evidence from geology and astronomy.
2.5 billion years: This is incorrect. While this is closer to the actual age, it is still significantly less than the scientifically accepted estimate.
2025 years: This is incorrect. This age is far too young and is more representative of the time since the beginning of the Common Era.
4.5 billion years: This is correct. Scientific evidence, including radiometric age dating of meteorite material and Earth rocks, supports the estimate that the Earth is approximately 4.5 billion years old.

In summary, the Earth is estimated to be about 4.5 billion years old based on scientific research and evidence.
