Solution
The correct option is D a- Scala media- Endolymph
b- Scala tympani - Perilymph
Cochlea is part of the inner ear. The cochlea is a coiled, fluid-filled tube that is split into three chambers by two membranes, Reissner’s membrane and the basilar membrane.
These two membranes divide the perilymph into an upper scala vestibuli and a lower scala tympani. The space within cochlea called scala media which is present between scala vestibuli and scala tympani is filled with endolymph.
‘a’ is scala media and it is filled with endolymph. ‘b’ is scala tympani and is filled with perilymph.
