base of telencephalon
B
roof of metencephalon
C
roof of diencephalon
D
base of myelencephalon
Answer
roof of diencephalon
Explanation
Solution
The diencephalon develops from the back of the forebrain and is located between the cerebral hemispheres and above the midbrain. It generally surrounds the third ventricle and is composed largely of grey matter organised into nuclei. Among these, a dense nucleus, called the thalamus/ bulges into the third ventricle from each side. Another region that includes many nuclei is the hypothalamus/ which lies below the thalamic nuclei and forms the lower walls and the floor of the third ventricle.
