C. Evolution is a change of allele frequency from one generation to the next
Explanation:
Evolution is the gradual change that occurs to living organisms over successive generations. According to Charles Darwin, these changes aid in the adaptation of the species of an organism to their environment. In other words, it makes them better fit.
Charles Darwin further stated that since evolution is dependent on natural selection i.e selection of the best fit by environmental factors, the changes that the organism undergo are genetic. Hence, evolution is a change of allele frequency from one generation to the next.
