Which theory of the origin of the moon would be most supported if the moon had an irregular shape, like an asteroid? impact theory co-formation theory capture theory synchronous theory

Its the impact theory.

It suggests that the moon resulted from the collision of two protoplanets, or embryonic worlds. One of those was the just-forming Earth, and the other was a Mars-size object called Theia. The moon then coalesced from the debris, thus giving it its irregular shape.
