Which theory suggests that the moon and the earth formed at the same time from dust from the solar nebula that formed the sun?

impact theory
co-formation theory
capture theory
synchronous theory

co-formation theory    

Explanation:

According to co-formation, the moon and the earth were formed together at the same time from dust present in the solar nebula. Because of gravity, the material was bound together-one formed the earth and other smaller object was moon. According to this theory, the composition of moon and Earth should be same. This theory also explained the location of the moon with respect to the Earth.
