Which statement best explains why multi cellular organisms have an advantage over single celled organisms

Well their best advantage would be that the multicellular organism can grow to any size it wants it wants because the cells integrate their activities and they are permanently associated with one another unlike the single celled organisms.

i don't see a text, but i am gonna assume this *orbit* the curved path, usually elliptical, described by a planet, satellite, spaceship, etc., around a celestial body, as the sun.
