In your own words. what kind of advantage does being
multicellulargive an organism?

An important advantage is the division of the work of the cells present in these organisms, saving energy and giving efficiency to the organism.

Being multicellular gave them an advantage over predation, for example, algae being larger were more difficult to eat.

This multicellular condition also allows them to feed on larger prey.

On the other hand, being multicellular gives them greater mobility by having more complex nervous systems.  The evolution of multicellular organisms allowed an expansion in the colonization of new niches.

the correct answer is - d. china has a large and growing population.

the fact that china has a large (the biggest) population, and it is still growing, doesn't hinder the agriculture production in the country. in fact, it can for increased production in the agriculture, since there's more labor force, as well the sheer mass of people produces lots of scientists that come up with new inventions as to how to improve this sector. nice example is the inner mongolia region in china, in general dominated by the gobi desert, but few scientist came up with a nice idea as to how to make the region productive by using plants that are very resistant to droughts, so lots of people have been employed, and the region is becoming greener and greener each year, and the production of food in this region is also increasing.
