This question is asking what controls the circadian rythm - the answer is Suprachiasmatic Nucleus.

just a fact- RYTHM is the longest word you can write without using any vowels .. it kinda helps me remember that the rythm is controlled by a long word (suprachiasmatic nucleus) lol

B. Suprachiasmatic Nucleus .

The correct answer is B.
Circadian rhythms are regulated by the suprachiasmatic nucleus, which is located in the hypothalamus. The supraoptic nucleus aids in thirst and water homeostasis. The frontal lobe is important for coordinating thought and behavior. The basal ganglia are associated with a variety of motor, cognition, and learning functions. The fourth ventricle allows CSF to exit via the midline foramen of Magendie or either of 2 lateral foramina of Luschka.
