A
True
B
False
C
Either A or B
D
None of the above
Explanation: 

Detailed explanation-1: -The ear is a sensory organ that picks up sound waves, allowing us to hear. It is also essential to our sense of balance: the organ of balance (the vestibular system) is found inside the inner ear.

Detailed explanation-2: -The organs of balance in the inner ear are called the vestibular system. This system includes three fluid-filled loops (semi-circular canals) which respond to the rotation of the head. Near the semicircular canals are the utricle and saccule, which detect gravity and back-and-forth motion.

Detailed explanation-3: -Many structures in the inner ear, called the vestibular system together, send signals to the brain, helping you to align yourself and keep your balance. Two parts of the inner ear called the utricle and the saccule track the head’s angular motions (from side to side and up and down), and sense gravity, too.

Detailed explanation-4: -Sound waves enter the outer ear and travel through a narrow passageway called the ear canal, which leads to the eardrum. The eardrum vibrates from the incoming sound waves and sends these vibrations to three tiny bones in the middle ear. These bones are called the malleus, incus, and stapes.
