When the iris relaxes and reduces the size of the pupil, then your eye acclimatizes to the bright light and the squinting stops.
The correct answer is option c. the sensory receptors in the vestibular sacs.
The kinesthetic system is involved in the movement and the balancing of the body. The mechanoreceptors present in the inner ear helps in determining the balance and the maintenance of the postures.
The vestibular sac have utricle and saccule, which help in the detection of the changes in linear acceleration. The semilunar canal present in inner ear respond to angular moments
