Solution

The correct option is D Corpus callosum
A deep cleft divides the cerebrum longitudinally into two halves, which are termed as the left and right cerebral hemispheres. The hemispheres are connected by a tract of nerve fibres called corpus callosum.
The dorsal portion of the midbrain consists mainly of four round swellings (lobes) called corpora quadrigemina.
