Solution
The correct option is B Pineal body
Corpora arenacea (or brain sand) are calcified structures in the pineal gland and other areas of the brain, such as the choroid plexus, whose function is unknown. Concentrations of brain sand increase with age, so the pineal gland becomes increasingly visible on X-rays over time. Chemical analysis shows that they are composed of calcium phosphate, calcium carbonate, magnesium phosphate and ammonium phosphate.
