Forms a provirus. virus attaches to the host using specific receptors on the cell membrane. viral dna integrates with the host cell dna forming a provirus. can remain dormant for months or years, spreading the infection to daughter cells during mitosis.

This process is called as the malignant transformation, which is described as below;

Malignant transformation:The DNA of which (pro-virus) is integrated into the chromosomal DNA of the host cell. As the pro-virus may lay dormant for a  much longer duration, and can hide it self by suppressing its genes. Now as they grow in number, they are able to infect other organs as well because there DNA is also replicating along with the host cell.

In general, cells with integrated pro-viral DNA are converted into cancer cells.

Explanation:

b - the respond is innate and varies over time.

good luck!
