**Core Concept**
The treatment of choice for T2 carcinoma of the nasopharynx involves a multidisciplinary approach, considering the stage, location, and patient's overall health. **Intensity-Modulated Radiation Therapy (IMRT)** is a crucial component in the management of nasopharyngeal carcinoma, as it allows for precise targeting of the tumor while minimizing damage to surrounding tissues.

**Why the Correct Answer is Right**
IMRT is the preferred treatment modality for T2 nasopharyngeal carcinoma due to its ability to deliver high doses of radiation to the tumor while sparing critical structures such as the optic nerves, chiasm, and brainstem. This is particularly important in the nasopharynx, where the tumor is located in close proximity to these vital structures. IMRT also reduces the risk of xerostomia (dry mouth) and other side effects associated with traditional radiation therapy.

**Why Each Wrong Option is Incorrect**
**Option A:** This option is incorrect as it does not specify a treatment modality and is too vague. Treatment of nasopharyngeal carcinoma requires a more targeted approach.
**Option B:** This option is incorrect as it is a surgical approach, which may not be the most effective treatment for a T2 tumor. Surgery may be reserved for residual or recurrent disease.
**Option C:** This option is incorrect as it is a chemotherapy regimen, which may be used in conjunction with radiation therapy but is not the primary treatment for T2 nasopharyngeal carcinoma.

**Clinical Pearl / High-Yield Fact**
It's essential to note that the treatment of nasopharyngeal carcinoma has evolved over time, and IMRT has become the standard of care for early-stage disease. This is due to its ability to improve local control and reduce toxicity.

**Correct Answer:** C. Chemoradiation (using IMRT) is the preferred treatment modality for T2 nasopharyngeal carcinoma.
