The correct option is D. Volcanic eruption released large amounts of water vapor into Earth's early atmosphere.
Earth’s first atmosphere had lots of water vapor but it almost lacked oxygen. Eventually, frequent volcanic eruptions put several different gases into the air. These gases created a new type of atmosphere for Earth. The volcanic eruptions spewed gases such as nitrogen, carbon dioxide, hydrogen, and water vapor into the atmosphere, but no free oxygen. Without oxygen, there could not be life on Earth.
