Hint: A doctor who has special training in the diagnosing and treating the disease in ear, nose and throat will be called as ENT specialist. ENT means Ear, Nose and Throat. It is also called Otolaryngology. Otolaryngologists are the physicians who are well trained in medical and surgical management and treatment of patients will have disorders in ear, nose and throat.

Complete step by step solution
The mirror which is used by the ENT specialist (Otolaryngologist) is a concave mirror. Because the concave mirror combines all the rays from the object and focuses the object rays in the desired part of the eye. So, that the object is very clear and bright to the ENT specialist (Otolaryngologist).

The concave mirror adjusts the light rays which are coming at the different angle. Once the rays from the object meet the concave mirror the rays get deflected and focused to the desired part (retina) of the eye. So, that the Otolaryngologist will see the object perfectly.

The usage of the concave mirror is very helpful to the Otolaryngologist during surgery in ear, nose and throat. The special characteristic of the concave mirror is, which helps to see the long and small object clearly.

Hence, the option (B) is correct.

Note: The inside parts of the ear, nose and throat are very small. So, the concave mirror helps to see the small parts clearly at the time of surgery. Thus, the concave mirror helps the doctor for clear vision and plays a major role in the medical treatments.
