Currently, the only place in the solar system where known life exists is Earth. In 2018, NASA released information that one of Jupiter's moons might be a good place to seek out possible life. What is the most likely reason that NASA thinks this moon could be a good place to look for life?

• The moon has a probable iron core.

• The moon is similar in size to the Earth's moon.

• The moon has a liquid ocean.

• The moon is in the same habital zone as the Earth.

• Nitrogen, Oxygen, Carbon Dioxide

• Methane, Oxygen, Helium

• Helium, Hydrogen, Oxygen

• Ammonia, Helium, Methane
