Explanation:

The problem is about the estimated age of the universe, which falls under the subfield of Physics (Natural Science). Scientific consensus based on cosmological observations (like cosmic microwave background radiation, expansion rate measurements) indicates the universe is approximately 13.8 billion years old. 4.6 billion years is the age of Earth, 100 billion is incorrect, 2 million is too young, and the infinite age idea is not supported by current cosmology.

Answer:

E. about 13.8 billion years
