Answer

Answer:

C. vestigial structures

Brief Explanations:

Vestigial structures are remnants of organs or structures that had a function in an ancestor but are now non - functional or have reduced function. Whales have pelvic and femur bones which are vestigial as they are no longer used for walking on land like their land - dwelling ancestors.
