The definition of mutation is "any heritable change in the genetic material." The qualifier "heritable" is necessary because:

A)most changes in the genetic material are harmful to the organism.
B)changes in the genetic material occur at random along the genome.
C)changes in the genetic material occur without regard to the needs of the organism.
D)most changes in the genetic material are repaired soon after they occur.
