Natural selection acts on phenotypes, but it favors the survival and reproduction of individuals with advantageous genotypes. It does not assure the survival of every fit individual, but rather selects for traits that increase an individual's fitness. It does not always select for more complex forms, and in fact, simpler forms may be favored if they are more efficient. Choice C is true because natural selection favors traits that increase an individual's chance of surviving and reproducing, and younger individuals typically have more years to reproduce than older individuals, giving them a selective advantage.
