Final answer:
The lab animal species that are born fully haired, with open eyes and ears, and with teeth are Guinea pigs.
Step-by-step explanation:
The members of this rodent lab animal species that are born fully haired, with eyes and ears open, and with teeth are Guinea pigs (Option D). Unlike other common lab rodents like hamsters, rats, and mice, Guinea pigs are born in a much more developed state, which is known as precocial birth. This is in contrast to altricial species like mice and rats, where the newborns are usually hairless and with closed eyes and ears. Guinea pigs are often used in scientific research due to their docile nature and ease of handling.
