C, D, E

Explanation:

Evolution is never completely random many traits contribute to it and persuade it, evolution is never perfect as many animals come out different and some don’t have the traits at all, and the only way for one to evolve is to have a variation of traits to persuade a new one, and the goal of evolution is to make better offspring than the last ones, an natural selection will eventually integrate to evolution if it is necessary to that environment.
