Answer 1

The correct option is C covering and protecting eye from water and mud

Apart from the eyelid, a transparent membrane called the nictitating membrane is present in amphibians such as frogs. It helps in protecting the eyes of the amphibians from water and mud while swimming in water. It also helps in keeping the eyes moist when the frog is on land.
