e. a and b only

Answer 1

B. Olfactory sense relay

Step-by-step explanation:

The mammillary bodies are the two small round shaped projections. Mammillary bodies and posterior hypothalamic nuclei together make the mamillary region and lie posterior to the hypothalamus. The function of mamillary bodies is to serve as relay center for reflexes related to olfaction, which is the sense of smell. The mammillary bodies also receive information related to olfaction from the hippocampus and serve in memory recollection.
