Answer:
c. Directional selection
Explanation:
Directional selection is a type of natural selection that occurs when selective pressure favors one extreme phenotype over any other phenotype existing in a population. Only one extreme phenotype is favored over time.
A good example of directional selection is the natural selection that occurs in giraffes, where alleles for long necks were favored against alleles for short necks as a result of selection pressure among the different phenotypes. Over time, giraffes having long necks dominated the population as the distribution of length of neck shifts towards the phenotype for long necks.

The appropriate answer is EXCRETION. Excretion is the process by which metabolic waste products are eliminated from the body. Living things take in molecules from the environment and chemically change them into molecules that form their own structures, control their physiology and provide them with energy. Metabolism is the sum of these reactions. These reactions produce waste material that can be toxic to cells if they accumulate. Metabolism therefore requires the process of excretion.
