Answer 1

The Correct Option is B

Concept:
Malware (malicious software) is an overarching term for programs designed to disrupt, compromise, or gain unauthorized access to computer systems and personal data.

Step 1: Analyzing Each Malware Type:
- (A) Keylogger: Software or hardware designed to monitor and record every keystroke made by the user, storing credentials and sensitive inputs to transmit them to an unauthorized party. Thus, (A) maps to (II).
- (B) Adware: Software that displays unwanted advertisements and generates revenue for its author on a pay-per-click basis. Thus, (B) maps to (I).
- (C) Spyware: Software that covertly tracks user activity, internet browsing history, and habits, typically monetizing this behavioral data by selling it to third-party marketing agencies. Thus, (C) maps to (IV).
- (D) Worm: A self-contained, standalone malicious program that autonomously replicates itself across networks without needing a host file or user activation. Thus, (D) maps to (III).

Step 2: Verifying the Matches:
The matching pairs are: \[ \text{(A)-(II), (B)-(I), (C)-(IV), (D)-(III)} \] Final Answer:
This matches option (B).
