D. They both decrease genetic variation.

Explanation:

In natural selection, variation happens to produce more fit organisms. The natural selection is a different type such as stabilizing selection, directional selection, and disruptive selection. In both cases, variation occurs but the variation rate is different. Therefore, the common thing between stabilizing selection and disruptive selection is variation. The variation rate is slow in stabilizing selection. Hence in this selection less phenotype characters are seen. In disruptive selection, variation is random and extreme. Thus more phenotype individuals are formed due to disruptive selection.

Answer from: Quest

you are certainly talking about this picture:

a: is the label of the white square, it is showing the replication fork, formed by helicase (d) ==> so it is the site of dna separation and replication

b: is a new dna brand that is following directly the replication fork, so it is continuous ==> built continuously from 5' to 3

c: dna polymerase cannot replicate dna on its own, it needs the of their proteins, and one of them plays the role of a clamp which fixes the dna with the dna template and increases the processivity of the enzyme. ==> stops polymerase from falling off the template.

d: is the enzyme responsible for forming the replication fork (helicase) ==> unwinds and separates dna into two strands

e: is the delayed strand, it is built in the opposite sense of the helicase, so dna will be built in fragments ==> built fragments from 5' to 3 joins

and finally f: is the enzyme that builds the new dna strand (dna polymerase) ==> adds nucleotides to make a new dna helix.
