Correct option is C
The correct answer is D → B → A → C → E.
1. The process of auditory information transmission begins in the organ of Corti (D), which is located in the cochlea of the inner ear and contains hair cells that convert sound vibrations into neural signals.
2. These signals are then transmitted to the cochlear nucleus and superior olivary nuclei (B) in the brainstem. The cochlear nucleus processes the auditory signal, and the olivary complex contributes to sound localization.
3. From there, the signal moves to the inferior colliculus (A) in the midbrain, which acts as a major auditory center involved in integrating spatial and temporal features of sound.
4. The signal then reaches the medial geniculate nucleus (C) of the thalamus, which serves as a relay station to the cortex.
5. Finally, the auditory information is transmitted to the primary auditory cortex (E) in the temporal lobe, where conscious perception and interpretation of sound occurs.

Key Components of Auditory Pathway
1. Organ of Corti (D):
Located in the cochlea; converts mechanical sound waves into electrical neural signals via hair cells.
Initiates the auditory transmission process.
2. Cochlear Nucleus and Olivary Nuclei (B):
First relay stations in the brainstem.
The superior olivary complex helps in sound localization by comparing signals from both ears.
3. Inferior Colliculus (A):
Acts as a central hub for auditory reflexes and integration, processing sound direction and timing.
4. Medial Geniculate Nucleus (C):
Located in the thalamus, serves as a relay center that forwards auditory input to the auditory cortex.
5. Primary Auditory Cortex (E):
Located in the superior temporal gyrus.
Responsible for perception of pitch, loudness, and sound interpretation.
