The correct option is B Utride and saccule - outer ear
The semicircular canals or semicircular ducts are three semicircular, interconnected tubes located in the innermost part of each ear, the inner ear. The three canals are the horizontal, superior and posterior semicircular canals.
The outer ear includes auricle (cartilage covered by skin placed on opposite sides of the head), auditory canal (also called the ear canal), eardrum outer layer (also called the tympanic membrane).
The middle ear includes eardrum, a cavity (also called the tympanic cavity), ossicles (3 tiny bones that are attached).
The inner ear includes: oval window - connects the middle ear with the inner ear, semicircular ducts - filled with fluid; attached to cochlea and nerves; send information on balance and head position to the brain, cochlea - spiral-shaped organ of hearing; transforms sound into signals that get sent to the brain, auditory tube - drains fluid from the middle ear into the throat behind the nose.
So, the correct answer is 'Utride and saccule - outer ear'.
