Best answer
Correct option is (a) Nictitating membrane

The explanation: Vestigial organs are the organs which are present in reduced form and do not perform any function in the body. Here, the nictitating membrane is an example of a vestigial organ. It is a translucent membrane that forms an inner eyelid in birds, reptiles, and mammals.
