Answer:
Option B, maculae/static equilibrium
Explanation:
The specialized sensory receptors of the macula are located in the utricle and saccule and are responsible for detecting the static equilibrium through their hair cells. The hair cells have large number of stereocilia and one single kinocilium which detects the movement of otolithic membrane caused by the release of calcium carbonate. The otolithic membrane moves up and down and to and fro.
Hence, option B is correct
