There is an ocean on Europa which contains liquid water. Other than the Earth, Europa is the only place in the solar system where we have found liquid water. Life as we know it is very dependent upon liquid water, and life is believed to have originally evolved in the water, before moving to the land.
This is @kanimalo correcting the answer... its actually D) water ocean and tidal energy
If there is liquid water on Europa, there might also be life.....

There may be life under Europa's vast oceans. It is cold, but heat from the moon's core and Jupiter's magnetic field may make it habitable for organisms under the ice.
Europa shows signs of having a saline environment, which could be amenable to life.
The movement of segments of Europa's icy surface, akin it Earth's tectonic plates, indicates that part of the interior is liquid water.
Why do astronomers think there could be life on Europa?
The scientists think that Europa can have the life on it.
There may be life under Europa's vast oceans. It is cold, but heat from the moon's core and Jupiter's magnetic field may make it habitable for organisms under the ice.
I have read somewhere that scientists think that europa may have an underground ocean.
Icy Caps
An icy surface.
They may have life.
A thick layer of ice
Europa is covered with ice and underneath a layer of ice there is an ocean that scientists think might have life living in it. Also Europa has many cracks on it.
Scientists believe that there is liquid water, under the crust of Europa.
Europa - a moon of Jupiter.
A saline ocean beneath it's crust.
As far was we know the development requires water in its liquid for to be present and a source of energy to supply/drive chemical reactions. We know that deep down Europa has a liquid layer (of water) and the geysers of this water into space proves that there is energy in Europa's core.
