Final Answer :
D
Explanation :
Cerumen (earwax) helps to protect the skin of the ear canal, protect the middle ear from bacteria, and enable cleaning and lubrication. However, it does not have a function in transferring sound waves from the eardrum to the incus. This is a function of the ossicles, which are small bones in the middle ear.
