**Core Concept**
Burkitt's lymphoma is a type of non-Hodgkin's lymphoma characterized by its rapid growth and aggressive behavior. It is primarily a B-cell malignancy, often associated with translocations involving the MYC gene.

**Why the Correct Answer is Right**
The correct answer is the region with the highest incidence of Burkitt's lymphoma. This is due to the endemic presence of the Epstein-Barr virus (EBV), which is known to contribute to the development of Burkitt's lymphoma. The MYC gene translocation, a hallmark of Burkitt's lymphoma, is also more frequently observed in this region. The high prevalence of malaria in this region is another contributing factor, as it may lead to chronic antigen stimulation, which in turn can trigger the development of lymphoma.

**Why Each Wrong Option is Incorrect**
**Option A:** This option is incorrect as it does not correspond to a known high-risk region for Burkitt's lymphoma.
**Option B:** This option is incorrect as it is not a region commonly associated with the highest incidence of Burkitt's lymphoma.
**Option D:** This option is incorrect as it is not a region with a known high prevalence of Burkitt's lymphoma.

**Clinical Pearl / High-Yield Fact**
Burkitt's lymphoma is often associated with a characteristic "starry sky" appearance under the microscope, due to the presence of apoptotic tumor cells and reactive lymphocytes. This appearance is a key diagnostic feature of the disease.

**Correct Answer: C. Africa.
