Best answer
Right choice is (a) cell division

Best explanation: There are mutations that alter the information of a single gene and then there are a whole range of alterations that chromosomes may be subjected to. Most of these alterations occur during cell division, when the chromosomal content is replicated and then distributed evenly among daughter cells.
