A provirus is viral DNA incorporated into the host cell’s DNA. In contrast, viral DNA refers to the genetic material of the virus itself, which may exist as a free, independent entity before it integrates into the host genome. Therefore, the key difference is that a provirus is integrated into the host cell's DNA, whereas viral DNA can exist in both integrated and unintegrated states within a host.

The correct statement is: **A provirus is viral DNA incorporated into the host cell’s DNA.**
To clarify the definitions:
1. A provirus is **not** bacterial DNA; it specifically refers to viral DNA that has been integrated into the genome of a host cell.
2. A provirus does **not** describe the host cell's DNA that has been destroyed; rather, it indicates that the viral DNA is now residing within the host's DNA.
3. A provirus is **not** simply newly replicated viral DNA after injection; it refers to viral DNA that is permanently incorporated into the host cell's genome.
4. The correct understanding of a provirus emphasizes its role in the host cell's DNA, making it a crucial part of the viral life cycle, particularly in lysogenic infections.
Thus, the comparison highlights that a provirus is a stage of viral DNA that has integrated into the host's genetic material, whereas general viral DNA can exist separately and may not yet be integrated.
