From what you currently know, in a spacecraft at a point of weightlessness, which effect is most likely?
A) Rotational equilibrium would be lacking and you could not detect head movement.
B) Gravitational equilibrium would be altered since the otoliths would not be pulled down by gravity.
C) Without gravity, there would be no vertigo.
D) All balance systems would work similar to being on Earth with normal gravity.
E) There would be absolutely no sense of balance signals of either type without gravity.

In a spacecraft at a point of weightlessness, the gravitational equilibrium would be altered since the otoliths would not be pulled down by gravity. The lack of gravitational pull would affect the ability of the otoliths to sense changes in head position, which can result in difficulty maintaining balance and orientation.
