D)A mummy's tooth

Question

Any tissue with a true nucleus, such as nasal epithelial cells, can provide DNA for genetic testing. The distal ends of hair shafts do not contain cells with a nucleus; only the hair root does. Mature red blood cells have no nucleus (and no mitochondria). A mummy's tooth would have enamel with no cells, and the tooth pulp would be long gone.
