**Core Concept**
Leprosy, also known as Hansen's disease, is a chronic bacterial infection caused by Mycobacterium leprae that primarily affects the peripheral nerves, skin, and mucous membranes. Leprosy is classified into different types based on the immune response of the patient, which determines the severity and clinical manifestations of the disease.

**Why the Correct Answer is Right**
Symmetrical multiple lesions are characteristic of tuberculoid leprosy, a type of leprosy that represents an intermediate form between the lepromatous and the tuberculoid poles of the leprosy spectrum. In tuberculoid leprosy, the immune response is relatively preserved, leading to the formation of granulomas around the bacteria, which results in the development of symmetrical skin lesions. The lesions in tuberculoid leprosy are typically well-defined, firm, and hypopigmented, and may be accompanied by sensory loss and nerve thickening.

**Why Each Wrong Option is Incorrect**
* **Option A:** This option is incorrect because it does not accurately describe the type of leprosy characterized by symmetrical multiple lesions.
* **Option B:** This option is incorrect because it does not accurately describe the type of leprosy characterized by symmetrical multiple lesions.
* **Option D:** This option is incorrect because it does not accurately describe the type of leprosy characterized by symmetrical multiple lesions.

**Clinical Pearl / High-Yield Fact**
Tuberculoid leprosy is often associated with a good prognosis and a high likelihood of spontaneous recovery, whereas lepromatous leprosy has a poor prognosis and requires prolonged treatment.

**Correct Answer: C. Tuberculoid leprosy**
