Explanation / Answer
1)
The phases of venus results , that the venus planets orbit round the sun inside the earth.
(Venus orbits around the sun is correct.)
2)
Prallax of stars is the correct option which does not support earth revolves around the sun.
3)
Stars temperture is correct, from weins law, wavelength of spectral line is inversely proportional to its absolute temperature.
4)
Vega is correct, will probably only live from billions of years.
