**Core Concept**
Otospongiosis, also known as otosclerosis, is a type of bone dysplasia affecting the middle ear. It involves abnormal bone remodeling, leading to fixation of the stapes bone and subsequent hearing loss. The condition is known to have a genetic component.

**Why the Correct Answer is Right**
Otospongiosis is primarily inherited in an autosomal dominant pattern, although some cases may exhibit an autosomal recessive pattern. The genetic mutations involved are often associated with genes encoding proteins critical for bone remodeling and homeostasis, such as COL1A1 and COL1A2. These mutations can lead to abnormal bone formation and resorption, characteristic of otospongiosis.

**Why Each Wrong Option is Incorrect**
**Option A:** Autosomal recessive inheritance is not the primary pattern observed in otospongiosis.
**Option B:** X-linked inheritance is not typically associated with otospongiosis.
**Option C:** Mitochondrial inheritance is not a known pattern for otospongiosis.

**Clinical Pearl / High-Yield Fact**
It's essential to recognize that otospongiosis often presents bilaterally, even if one ear is more affected than the other. This is a key clinical feature that distinguishes it from other causes of hearing loss.

**Correct Answer: C. Autosomal dominant.
