The correct answer is: A predator prefers one phenotype to another.
There are variations in every population meaning that individuals are different at both, genetic and phenotypic level.
Natural selection is one of the evolutionary mechanisms, meaning that it changes allele frequency over generation. There must be genetic variation in population so that the natural selection can act. Natural selection acts on an organism’s phenotype (observable features) by favoring the most suitable ones (for survival).
If predator prefers one phenotype to another, another phenotype helps organisms survive and reproduce so that organism is better adapted for the environment. Natural selection ”selects” the best adapted trait.
