Solution

The correct option is C Helicotrema
Helicotrema is a part of cochlea that separates scala vestibuli and scala tympani. The hair cells present near helicotrema can detect sounds of low frequencies. Helicotrema is present at the apex of cochlea and helps in the communication between scala vestibuli and scala as the perilymph of these two canals are connected through helicotrema.
So, the correct answer is 'Helicotrema'.
