**Core Concept**
The management of cervical dysplasia involves a multi-step approach to prevent the progression to invasive cervical cancer. The primary goal is to eliminate high-risk human papillomavirus (HPV) infection, which is the underlying cause of cervical dysplasia.

**Why the Correct Answer is Right**
The treatment of choice for severe cervical dysplasia is **loop electrosurgical excision procedure (LEEP)**, which involves the removal of the abnormal cervical tissue using a wire loop. This procedure is effective in removing the dysplastic cells and obtaining a histopathological diagnosis. Additionally, LEEP allows for the concomitant removal of the transformation zone, where most cervical cancers originate. The removal of the transformation zone also enables the evaluation of the underlying cervical tissue for signs of invasive cancer.

**Why Each Wrong Option is Incorrect**
**Option A:** **Cone biopsy** is a more invasive procedure that involves the removal of a cone-shaped sample of tissue from the cervix. While it can provide a more extensive histopathological evaluation, it is not the preferred initial treatment for severe cervical dysplasia.
**Option B:** **Antiviral therapy** is not an established treatment for cervical dysplasia. Although HPV infection is the underlying cause of cervical dysplasia, antiviral medications have not been shown to prevent the progression to invasive cancer.
**Option C:** **Hysterectomy** is a radical surgical procedure that involves the removal of the uterus. While it may be considered in cases of advanced cervical cancer, it is not the initial treatment of choice for severe cervical dysplasia.

**Clinical Pearl / High-Yield Fact**
It is essential to note that the management of cervical dysplasia requires a multidisciplinary approach, involving gynecologic oncologists, pathologists, and primary care physicians. The American College of Obstetricians and Gynecologists (ACOG) recommends regular cervical cancer screening for women aged 21-65 years to detect cervical dysplasia and prevent invasive cancer.

**Correct Answer:** C.
