lateral and medial geniculate nuclei
mainly supplied by "posterior cerebral artery"few branches from "posterior communicating artery" and "inferior choroidal artery"
It does not consist of nuclei

Specific nuclei of the thalamus are a group of nuclei that have well-defined connections with specific regions of the cerebral cortex. Examples include the ventral posterolateral nucleus (VPL), which relays sensory information to the somatosensory cortex, and the lateral geniculate nucleus (LGN), which relays visual information to the primary visual cortex.
The hypothalamus is inferior to the thalamus. It is posterior(in back) of the optic chiasm beside the temporal lobes and optic tracts.
A basal ganglion is any of a group of nuclei in the brain interconnected with the cerebral cortex, the thalamus and the brainstem.
from spinal nerve to posterior (dorsal) root
It depends on which group of thalamic nuclei that you are referring to.anterior group of nuclei = relay station for hippocampal impulsesmedial group of nuclei = relay station for visceral impulsesanterior ventral group of nuclei = relay station for extrapyramidal impulsesintermediate ventral group of nuclei = relay station for cerebellar impulses concerned with integration of muscle tonepostero-lateral ventral group of nuclei = relay station for exteroceptive impulses & proprioceptive impulses from the opposite side of the body below the headpostero-medial ventral group of nuclei = relay station for exteroceptive and proprioceptive impulses from opposite side of headinterlaminar + midline + reticular nuclei = participate in the arousal reactions of the brain
optic part, which contains 2 nuclei = supraoptic + paraventricular nucleituberal part, has 3 nuclei = ventromedial + dorsomedial + tubral nucleimamillary part, has 2 nuclei = posterior + lateral nucleiposterior perforated substance
Option 'a' is correct.
The hypothalamus is made up of several small nuclei. There are many different functions of this nuclei including linking the nervous system to the endocrine system.
The major blood supply to the midbrain, occipital lobe, and thalamus primarily comes from the posterior cerebral artery (PCA). The PCA branches off from the basilar artery and provides oxygenated blood to these regions of the brain. Additionally, branches from the posterior communicating artery can also contribute to the vascular supply of these areas.
