mutations which are changes in the original code of dna are an example of which of the four components of natural selection?
○ competition
○ reproduction
○ variation
○ selection

Explanation:

The four components of natural selection are variation, inheritance, high rate of population growth (leading to competition), and differential survival and reproduction (selection). Mutations introduce changes in DNA, which create differences (variation) among individuals in a population. Competition is about organisms competing for resources, reproduction is the process of producing offspring, and selection is about differential survival/reproduction. So mutations relate to variation.

Answer:

C. variation
