Oncogenic virus

• ✅ Retroviruses can integrate and mutate host genes.
• ✅ Some carry immune-evading genes.

But you missed this valid choice:

• ✅ Oncogenic viruses can cause long-term infections, creating chronic inflammation which increases the risk of developing cancer.

This is true, especially for viruses like Hepatitis B and C, which cause long-term liver inflammation and increase cancer risk.

🛠️ Fix: Also select the chronic inflammation option.
