**Core Concept**
Neurocysticercosis is a parasitic infection caused by the tapeworm Taenia solium, resulting in the formation of cysts in the brain. This condition is a leading cause of adult-onset epilepsy in developing countries.

**Why the Correct Answer is Right**
The larval stage of T. solium, known as cysticerci, invades the brain tissue and forms cysts. These cysts can be found in various locations, including the cerebral cortex, basal ganglia, and cerebellum. The immune response to the cysts can lead to inflammation, scarring, and seizures. The correct answer is related to the pathophysiology of neurocysticercosis, specifically the role of the immune response in causing seizures.

**Why Each Wrong Option is Incorrect**
* **Option A:** This option is incorrect because it does not accurately describe the pathophysiology of neurocysticercosis. The condition is not primarily caused by an allergic reaction, but rather by the invasion of the brain by cysticerci.
* **Option B:** This option is incorrect because it does not mention the role of the immune response in causing seizures. While inflammation is a component of neurocysticercosis, it is not the primary cause of seizures.
* **Option C:** This option is incorrect because it does not accurately describe the location of cysts in the brain. Cysts can be found in various locations, including the cerebral cortex, basal ganglia, and cerebellum.

**Clinical Pearl / High-Yield Fact**
A key clinical feature of neurocysticercosis is the presence of a "raccoon sign" on imaging studies, which refers to the presence of calcifications in the brain. This sign is often seen in patients with calcified cysts.
