**Core Concept**
The management of single lesion in leprosy eradication programs focuses on early detection and treatment to prevent the spread of the disease. Leprosy, caused by Mycobacterium leprae, primarily affects the skin, nerves, and mucous membranes, and can lead to significant disability if left untreated.

**Why the Correct Answer is Right**
The correct approach is to administer a single dose of rifampicin (600 mg) along with clofazimine (50 mg) and dapsone (100 mg) for 6 months. This regimen is effective in treating single lesions early, reducing the risk of nerve damage and disability. Rifampicin acts by inhibiting bacterial RNA synthesis, while clofazimine and dapsone have antimicrobial properties that target the leprosy bacillus.

**Why Each Wrong Option is Incorrect**
**Option A:** This option is incorrect because it does not specify the correct antibiotic regimen for single lesion management in leprosy eradication programs.
**Option B:** This option is incorrect because it does not provide a clear treatment protocol for single lesions, which is a critical aspect of early management.
**Option C:** This option is incorrect because it does not mention the use of clofazimine, which is a crucial component of the recommended treatment regimen.

**Clinical Pearl / High-Yield Fact**
It's essential to note that a single dose of rifampicin, along with clofazimine and dapsone, is effective in treating single lesions in leprosy eradication programs, and this approach can help prevent long-term disability.

**Correct Answer:** C.
