**Core Concept**
Human Papillomavirus (HPV) is a DNA virus that causes persistent infection in cervical epithelial cells, leading to cellular changes. The virus exploits the host cell's machinery to promote its own replication, resulting in uncontrolled cell growth.

**Why the Correct Answer is Right**
HPV causes immortalization of epithelial cells by manipulating the cell cycle and preventing apoptosis. The virus's oncogenic proteins, such as E6 and E7, bind to and inactivate the tumor suppressor proteins p53 and Rb, respectively. This leads to the accumulation of mutations and the activation of telomerase, allowing infected cells to divide indefinitely. As a result, the cervical epithelium becomes neoplastic, increasing the risk of cervical cancer.

**Why Each Wrong Option is Incorrect**
* **Option A:** Induction of apoptosis is actually inhibited by HPV, not induced. The virus's E6 and E7 proteins prevent the activation of pro-apoptotic pathways.
* **Option B:** Necrosis is a form of cell death that is not directly associated with HPV infection. While apoptosis is inhibited, necrosis is not a characteristic change in cervical epithelium caused by HPV.
* **Option D:** Telomerase is indeed activated in HPV-infected cells, but this is a consequence of immortalization, not the cause. Telomerase activation is a result of the viral oncogenes' ability to promote cell proliferation and prevent apoptosis.

**Clinical Pearl / High-Yield Fact**
HPV infection is a common cause of cervical cancer, and the virus can persist in the host for decades before causing neoplastic changes. The development of cervical cancer is a multi-step process, involving the accumulation of genetic mutations and the inactivation of tumor suppressor proteins.

✓ Correct Answer: C. Immortalization of epithelial cells
