Correct answer: D
CONCEPT
Malware types are distinguished by how they spread or hide and by what activates their payload. A worm self-replicates across networks; a Trojan Horse carries a covert function; a logic bomb waits for a condition; and a rootkit conceals malware by intercepting operating-system functions.
APPLICATION
Malware type | Defining characteristic |
|---|---|
Trojan Horse | Contains an unexpected covert effect (IV) |
Worm | Propagates copies of itself through a network (I) |
Logic Bomb | Triggers an action when a specified condition occurs (II) |
Rootkit | Hooks standard operating-system calls to hide malware (III) |
CROSS-CHECK / CONTRAST
A-I, B-IV, C-III, D-II assigns network propagation to the Trojan Horse and a covert effect to the worm, reversing their defining behaviours.
A-IV, B-II, C-I, D-III assigns conditional activation to the worm and network propagation to the logic bomb.
A-II, B-I, C-III, D-IV assigns conditional activation to the Trojan Horse, OS-call concealment to the logic bomb, and a covert effect to the rootkit.
Therefore, the consistent matching is A-IV, B-I, C-II, D-III.
