Answer 1

On E2020 the correct answer is B. I just took the quiz.

Answer 2

The correct answer is (b)The vestibular sense may be capable of sensory adaptation

Astronauts experience similar feelings of dizziness and disorientation upon arrival in space and upon their arrival back on Earth because the vestibular sense may be capable of changing adaptation. The dizziness and disorientation is due to the floating fluid in inner ear around zero gravity and it goes right away after some time when the astronauts reach the space. The adaptation is done by the brain to ignore the signals of the ear; the feeling this sensation for sometime the brain becomes adaptable and does not listens to the inner ear every time. This is a kind of sensory adaptation.
