Which theory suggests that the moon and the earth formed at the same time from dust and the solar nebula that formed the sun?
a.) impact theory
b.)co formation theory
c.) capture theory
d.) synchronous theory

The correct answer is option(B.).

Explanation:

The co-formation theory explain that both moon and the earth are formed at same time from the primitive solar nebula (cloud made up of dust and gases)  at the same and same place.

Where as capture theory suggests that the moon is an asteroid which was formed or created somewhere else in a solar system. And when the moon approached the earth planet it got captured by the earth's gravitational field.

Impact theory explains the formation of moon by the catastrophic collision between the earth and any planet half the size of earth's size.

Synchronous theory sheds the light on the rotation time, revolution time and sides of moon located from the surface of the earth.

Hence, the correct answer is option(B).
