**Core Concept**
The t(8;14) translocation is a chromosomal abnormality involving the long arms of chromosomes 8 and 14, leading to the juxtaposition of the MYC gene on chromosome 8 with the immunoglobulin heavy chain gene on chromosome 14. This results in the overexpression of the MYC gene, which is a potent oncogene.

**Why the Correct Answer is Right**
The MYC gene plays a critical role in cell proliferation and differentiation, and its overexpression is associated with the development of various cancers, including Burkitt lymphoma. The t(8;14) translocation creates a fusion gene that drives the expression of MYC, leading to uncontrolled cell growth and tumor formation.

**Why Each Wrong Option is Incorrect**
**Option A:** This option is incorrect because the t(8;14) translocation does not involve the BCL2 gene, which is associated with follicular lymphoma and is characterized by a different chromosomal translocation (t(14;18)).

**Option C:** This option is incorrect because the t(8;14) translocation does not involve the REL gene, which is associated with anaplastic large cell lymphoma and is characterized by a different chromosomal translocation (t(2;5)).

**Clinical Pearl / High-Yield Fact**
Burkitt lymphoma is a highly aggressive B-cell lymphoma that is often associated with the t(8;14) translocation and is characterized by a rapid doubling time of cells, leading to a high risk of relapse if not treated promptly.

**Correct Answer: B. MYC**
