• D. Cochela contains $16000$ to $24000$ hairs cells arranged in four rows

Answer 1

The correct option is C The middle and lower chamber communicate through helicotroma

The helicotrema is the part of the cochlear labyrinth where the scala tympani ( lower chamber ) and the scale vestibule meet ( upper chamber ). It is the main component of the cochlear apex. The hair cells near this area best detect low-frequency sounds.

So, the correct option is 'The middle and lower chamber communicates through helicotrema'.
