On the surface of Jupiter's moon Europa, water remains frozen, but the gravitational force of Jupiter and its other moons cause contractions that may generate so much heat that it would melt ice below Europa's surface.

A). moons cause contractions that may generate so much heat that it would melt
B). moons cause contractions, with enough heat generated for melting
C). moons causes contractions that may generate enough heat to melt
D). moons, causing contractions, may generate so much heat to melt
E). moons, which causes contractions, may generate enough heat for melting

OA after discussions.
