B.
A strong atmosphere was present before the volcanic activity.

C.
Water vapor in the atmosphere increased once precipitation began.

D.

Answer 1

The data suggests that volcanic outgassing does not fully explain the total amount of water vapor and other gases in Earth's early atmosphere. This implies that additional sources are likely responsible for the presence of these gases, supporting the idea that external bodies contributed to the atmosphere’s composition.

Thus, the scientific claim that is best supported by this data is:

**D. Comets and asteroids brought various gases to Earth's atmosphere.**
