Why each option

A logic bomb is malware that remains dormant until a specific predetermined condition or event triggers its execution. It is distinct from other malware types that activate immediately or spread autonomously.

ATrojan horse

A Trojan horse disguises itself as legitimate software to trick users into executing it, but it does not wait for a predetermined event trigger.

BLogic bombCorrect

A logic bomb is code inserted into a system that lies dormant until a specific triggering condition is met - such as a date, time, user action, or system event - at which point it executes its malicious payload.

CMAC

MAC (Mandatory Access Control) is an access control security model, not a type of malware or executable code tied to event triggers.

DWorm

A worm self-replicates and spreads across networks continuously without waiting for a specific predetermined triggering event.
