Correct Answer: A. mutation
Explanation
Mutation is the process by which there is a permanent alteration in the DNA sequence of an organism's genome.

Mutations can happen in somatic cells, which affect only the individual, or in germ cells (egg or sperm cells), which can be passed on to offspring.
