Hints & Solutions
(b) Option (b) is correct because organ of Corti is located on the basilar membrane, thus (a) in column-I matches with (iv) in column-II. Cochlea, so (b) matches with (ii) in. The coiled portion of the labyrinth is called column II.
These three bones, often referred to as the ossicles, serve a crucial role in moving sound waves from your outer ear to your inner ear. Without your ossicles, you wouldn’t be able to hear as you do now. All sound starts as sound waves. When a sound wave reaches your ear, it pushes up against the eardrum as vibrations.
