• B. Saccule
• C. Pinna
• D. Semicircular canals

Answer 1

Answer: (A), (B), (D)

The correct options are
A Utricle
B Saccule
D Semicircular canals

Sensory information about motion, equilibrium and spatial orientation are provided by the vestibular apparatus which consists the utricle, saccule and three semicircular canals. The utricle and saccule helps in detecting gravity (information in a vertical orientation) and linear movements. Semicircular canals are three tiny, fluid-filled tubes in our inner ear that help us maintain our body balance.
