Solution

The correct option is D Quadrigemina
The mid-brain or mesencephalon consists of optic lobes and crura ceribri. In frog, there are two optic lobes (corpora bigemina) which are hollow but in man, there are four solid optic lobes lying behind the dicencephalon. They collectively constitute the corpora quadrigemina.
