Answer

Brief Explanations:

Galileo observed the phases of Venus, similar to the Moon's phases. This could only be possible if Venus orbited the Sun, providing evidence for the heliocentric model where planets, including Earth, orbit the Sun. The other statements were not Galileo - made discoveries for this purpose. Kepler discovered that the orbits of the planets are elliptical. The idea about Earth's rotation causing the Sun to rise is a basic fact about Earth - Sun motion not specifically a discovery by Galileo to support heliocentrism. Kepler's laws describe the speed of planets in their orbits related to their distance from the Sun.

Answer:

Venus has phases.
