Answer:
A. when hair cells are bent against the tectorial membrane, causing them to depolarize and release neurotransmitter that stimulates sensory neurons.
Explanation:
This is the mechanism of propagation and transmission of sound waves as action potential to from the ear to auditory centres in the brain. This mechanism takes place in the inner ear( organ of corti, supported by basilar membrane.There are group of receptors in the Endolymph, whicha are hair cells supported by the tectorial membrane,.The organ of Corti acts as transducers in the inner ear and converts the circular fluid motion to electrical signals as action potential, when the hair cells bends against the tectorial membrane as a results of vibration of the endolymph The causes depolarization, and therefore action potential.
The potential is transmitted to the auditory centres in the brain for sound perceptions.

I think under the influence of Antidiuretic hormone (ADH), more concentrated urine is produced. Antidiuretic hormone also called vasopressin acts to maintain blood pressure, blood volume and tissue water content by controlling the amount of water and hence the concentration of urine excreted by the kidney increases. It also helps to control blood pressure by acting on the kidneys and the blood vessels.
