Which statement about worms is true?

Which statement about worms is true?

• A. Worms require user action to propagate.
• B. Worms can propagate across networks without user interaction.
• C. Worms only infect email attachments.
• D. Worms cannot replicate.

Answer: (B)

Worms are built to spread on their own by replicating and moving through networks without needing a user to click or open something. This autonomous propagation often happens by scanning for vulnerable machines, exploiting a flaw in a service, and then copying themselves to the new host, continuing the cycle without human action. That ability to replicate and spread across networked systems is what distinguishes worms from other malware that typically needs user interaction to propagate. The other statements don’t fit because worms aren’t limited to user actions, aren’t restricted to email attachments, and certainly can replicate. This is why propagating across networks without user interaction is the true behavior of worms.
