Final Answer :
D
Explanation :
The otoscope directs light into the ear canal and onto the tympanic membrane that divides the external and middle ear. An otoscope is not used to direct light on the sinuses and is not able to provide visualization of the structures of the internal ear. A short, broad speculum is used to visualize the nares, not the ear.
