The correct answer is option C- evolutionary changes
Changes in DNA sequence, either natural or induced, causes mutations. Mutations can lead to evolutionary change.
Sometimes mutations lead to disfunctioning of genetic material and the proteins translated whereas these changes can give birth to a new product which can be beneficial.
For example, a single mutation is amino acid can changed the structure and function of a protein which caused Sickle cell anemia.
THE OCEANS ARE so vast and deep that until fairly recently, it was widely assumed that no matter how much trash and chemicals humans dumped into them, the effects would be negligible.
