Solution

The correct option is B Spherical
The lens of the eye in frogs is circular or spherical. The iris can be round, oval or heart-shaped. The circular eyes are called as cephalopod eyes. These type of eyes have been developed in organisms living in aquatic environments. These eyes can move the camera lens by moving back and forth. Such eyes help in moving away from the predators.
So, the correct answer is option C.
