Answer:
The correct option is C) A change in the DNA produces a variation within the gene
Step-by-step explanation:
Mutations can be described as any changes which occur in the genome of an organism. A mutation can be heritable or non-heritable. The changes in the DNA caused by mutations might benefit the organism or they might harm the organism. If mutations cause changes in the introns, then the organism will not be affected at all. A mutation which makes an organism better adapted to live in an environment can be advantageous for the population of that species.
