**Core Concept**
Ototoxicity refers to the damage caused to the inner ear or auditory nerve by chemicals, medications, or other external agents. Certain conditions and medications can lead to varying degrees of hearing loss, depending on the severity and duration of exposure.

**Why the Correct Answer is Right**
The condition associated with maximum hearing loss is Otosclerosis. Otosclerosis is a type of bone growth in the middle ear that causes the stapes bone to become fixed, leading to a conductive hearing loss. This condition can cause a significant reduction in hearing thresholds, often requiring surgical intervention or hearing aids for management. The pathophysiology involves abnormal bone growth and fixation of the stapes bone, preventing normal sound conduction.

**Why Each Wrong Option is Incorrect**
* **Option A:** Meniere's disease is associated with a fluctuating sensorineural hearing loss, but it typically does not cause maximum hearing loss compared to otosclerosis.
* **Option B:** Noise-induced hearing loss can cause significant hearing loss, but it is typically not as severe as the conductive hearing loss associated with otosclerosis.
* **Option D:** Presbycusis refers to age-related hearing loss, which is a common condition but typically does not cause maximum hearing loss compared to otosclerosis.

**Clinical Pearl / High-Yield Fact**
Otosclerosis is a condition that can be associated with a family history, and genetic predisposition is a known risk factor. Patients with a family history of otosclerosis should be monitored closely for early signs of hearing loss.

**Correct Answer:** C. Otosclerosis
