Answer:
The correct answer is option b. "oncogenes".
Explanation:
Viral oncogenes are genetic materials that come from viruses responsible of development of cancer and oncogenesis: the persistent infection of virus. Human papillomavirus (HPV) is considered an oncovirus for having viral oncogenes and being a common cause of cancer. The more quickly HPV transforms into host cells the more likely it will express viral oncogenes, which helps the virus to keep infecting the cells and harms the host organism by causing cancer.
