Correct answer: C
Concept: Malware is short for "malicious software" and names an entire category, not a single program. Any code written to damage, disrupt, spy on, or gain unauthorised access to a computer, its data, or its network belongs to that category. Membership is decided by the intent behind the code, not by how the code spreads or what payload it delivers.
Application: each item named in this question is defined by exactly that malicious intent, so each one sits inside the category.
Item | How it works |
|---|---|
Virus | Attaches itself to a host file or program and replicates whenever that host is run, corrupting or altering data along the way. |
Worms | Self-propagating code that copies itself across a network on its own, needing neither a host file nor a user action. |
Ransomware | Encrypts or locks the victim's data and then demands a payment in exchange for restoring access to it. |
Trojan | Disguises itself as legitimate software so that the user runs it willingly, and then executes a hidden harmful payload. |
Cross-check: the boundary of the category is intent, not technique. A packet sniffer or a disk-wiping utility shipped as a legitimate administrative tool stays outside the category even though an attacker could misuse it, while every item listed here exists to damage, extort, or intrude. Since none of the four items can be pushed outside the category, any selection that leaves one out under-counts the list.
Result: all four statements — (A) Virus, (B) Worms, (C) Ransomware and (D) Trojan — name malware, so the selection covering (A), (B), (C) and (D) is the answer.
