Solution
The correct option is A Mammals
The corpora quadrigemina in mammals are four solid lobes on the dorsal side of the cerebral aqueduct, where the superior posterior pair are called as the superior colliculi and the inferior posterior pair is called the inferior colliculi. The four solid lobes help to decussate several fibres of the optic nerve. The optic lobes or corpora bigemina of fishes, batrachians and birds are structurally homologous with the corpora quadrigemina of mammals.
