The question is referring to primary succession, which begins with the colonization of living organisms in an area that hasn't had any living organisms before.
This kind of succession begins with microorganisms, and plants such as lichens and mosses.
Given that a rock outcrop is a terrestrial environment, lichens (C) are most likely to be the firsts organisms.
Eukaryotes can organize into multi-celled organisms.
No, the answer is false.
A salad would be an example of a mixture, as it is a blend of tomatoes and lettuce.
