According to the NCERT text:

1. Hypothalamus: Located in the Forebrain (specifically at the base of the thalamus). Its functions include controlling body temperature, urge for eating, and drinking. This matches Option B.
2. Cerebellum: Located in the Hindbrain, not Midbrain. The Medulla Oblongata controls respiration.
3. Blind Spot: Located where the optic nerve leaves the eye, but photoreceptor cells (rods and cones) are absent there.
