Whales have pelvic (hip) bones, which are evolutionary remains from when their forefathers walked on land about 40 million years ago. Common belief has long assumed that such bones are merely vestigial, slowly withering away like human tailbones. Thus option C is correct.
<h3>What is the new research from USC and the Natural History Museum of Los Angeles County (NHM) has to say ?</h3>
New research from USC and the Natural History Museum of Los Angeles County (NHM) contradicts this belief, discovering that not only do those pelvic bones have a role, but their size and perhaps shape are impacted by sexual selection processes.
Therefore, small, shrunken hip bones of whale are no longer beneficial for survival and are considered vestigial. So, the best option is C among the other options available. Thus option C is correct.

If the respiratory membrane is composed of two layers of

epithelium will serve as a protection against abrasion of which the respiratory
membrane will be protected of.
