A Correct answer
Explanation

There are ten pairs of cranial nerves arising from the brain. The brain is enclosed in a bony structure called brain box. The brain is divided into fore-brain mid-brain and hind-brain. Forebrain includes olfactory lobes, paired cerebral hemispheres, and unpaired diencephalon. The midbrain is characterized by a pair of optic lobes. Hind-brain consists of cerebellum and medulla oblongata. The ventricle opens into a sac-like conus arteriosus on the ventral side of heart.

So the correct option is "Parathyroid and pineal body are present".
