(D) The correct answer is $D$. In eukaryotes,mitochondrial inheritance is strictly maternal. During fertilization,the sperm contributes its nucleus to the egg,but the cytoplasm (containing mitochondria) is almost exclusively derived from the ovum. Since the parent with the mitochondrial mutation is used as the male,the mutation will not be passed on to the offspring. Therefore,none of the $F_1$ or $F_2$ progenies will inherit the mutation.
