Explanation
A virus is defined by its self-replicating behavior - it attaches itself to legitimate programs or files and spreads to other systems when those files are shared or executed, making replication its core characteristic.
B (Trojan) is wrong because a Trojan disguises itself as legitimate software to trick users into running it, but does not self-replicate or spread on its own - it relies entirely on the user to propagate it.
C (Spyware) is wrong because its purpose is covert surveillance (capturing keystrokes, credentials, browsing habits), not self-replication or spreading.
D (Adware) is wrong because adware's goal is delivering unwanted advertisements, not reproducing itself across systems.
Memory tip: Think of a biological virus - it infects a host and replicates to spread. The malware "virus" mirrors this exactly. If replication/spreading is in the question, think virus.
