Explanation:

Question 1 (Endocrine organ hanging from hypothalamus)

The pituitary gland is the endocrine organ that hangs down from the hypothalamus. The thalamus is a brain structure for relaying sensory info, the pineal gland is in the brain (not hanging from hypothalamus), and the corpus callosum connects brain hemispheres.

The organ of Corti is the receptor structure for hearing in the cochlea. The vestibule and semicircular canals are for balance, and the macula is for static equilibrium (balance) in the vestibule.

Cranial Nerve IX (Glossopharyngeal) transmits sensory data from the posterior third of the tongue. CN VII (Facial) handles anterior tongue taste, CN V (Trigeminal) handles facial sensation, and CN XII (Hypoglossal) controls tongue movement.

Answer:

C. Pituitary gland
