Which phase of the virus lifecycle does the virus replicate itself?

The correct phase in which a virus replicates itself is the propagation phase. During this phase, the virus actively spreads to other systems, making copies of itself as it attempts to infect additional files, programs, or systems.

The propagation phase follows the execution phase, where the virus's code runs and begins its malicious activities. Once activated, the virus will replicate itself, allowing it to spread. This is crucial for the virus's survival and the extent of its impact, as a successful replication increases its chances of infecting more hosts.

In contrast, the dormant phase is characterized by the virus being inactive or non-replicating, not taking any actions that would cause an infection or spread. The triggering phase involves conditions that cause the virus to execute and can lead to the propagation phase once the virus is activated.
