**Core Concept**
A blowout fracture is a type of fracture that occurs when there is a break in one or more of the bones surrounding the eye socket (orbit). It is typically caused by a direct blow to the eye or the orbital rim.

**Why the Correct Answer is Right**
A blowout fracture occurs when the bones of the orbit are unable to withstand the force of the impact, leading to a fracture. The orbital floor and medial wall are the most common sites for blowout fractures due to their thin composition. The orbital floor is particularly susceptible to fracture because it is made up of thin plate-like bones that can be easily compressed.

**Why Each Wrong Option is Incorrect**
**Option A:** This option is incorrect because a blowout fracture specifically involves the bones surrounding the eye socket, not the facial bones in general.
**Option B:** This option is incorrect because a fracture of the nasal bones would be classified as a nasal fracture, not a blowout fracture.
**Option C:** This option is incorrect because a fracture of the zygomatic bone would be classified as a zygomatic fracture, not a blowout fracture.
**Option D:** This option is incorrect because a fracture of the maxillary bone would be classified as a maxillary fracture, not a blowout fracture.

**Clinical Pearl / High-Yield Fact**
A blowout fracture can lead to entrapment of the orbital fat and muscles, resulting in a condition known as "herniation" of these structures into the maxillary sinus. This can cause symptoms such as diplopia (double vision) and enophthalmos (sinking of the eye).

**Correct Answer:** C.
