Answer:
The correct answer to the following question will be Option D (a worm).
Step-by-step explanation:
A PC worm seems to be a form of harmful, self-replicating software that often infects other machines while remaining onto corrupted devices.
- Worms may often go overlooked before their excessive propagation cycle utilizes machine resources, stopping the encrypted file as well as slowing it down.
- The virus is quickly spreading inside the company's servers leading the server or computer to fail.
The other three options are not related to the given scenario. So that Option D is the right answer.
