Answer:
Correct Answer: B
Solution:
Statocysts are a pair of small, white, bead-like structures.
A small statocystic branch of antennular nerve supplies the statocyst.
Statocysts perceive the direction of the force of gravity and function as the organs of orientation and equilibrium.
Stimulated setae present in statocyst convey the information to brain through nerves, so that the animal corrects its position.
