Question

Given below are two statements: Assertion (A): A virus is a piece of software code created to perform malicious activities and hamper resources of a computer system. Reason (R): Some of the well-known viruses include CryptoLocker, ILOVEYOU, MyDoom, Slammer etc. Choose the most appropriate answer.

• A. Both (A) and (R) are correct and (R) is the correct explanation of (A)
• B. Both (A) and (R) are correct but (R) is not the correct explanation of (A)
• C. (A) is correct but (R) is not correct
• D. (A) is not correct but (R) is correct

Hint:

In assertion-reason questions, examples may support a statement, but they may not always explain the reason behind it.

Answer 1

The Correct Option is B

Step 1: Understanding the Question:

• This question consists of an Assertion and a Reason regarding malicious computer programs, commonly referred to as computer viruses or malware.

• We need to evaluate if both statements are factually correct and then determine if the Reason explains why the Assertion is true.

Step 2: Detailed Explanation:

• Evaluating Assertion (A): A computer virus is a type of malicious software (malware) designed to replicate itself by attaching to other programs, executing unauthorized commands, deleting files, consuming system resources, or causing security breaches. Thus, Assertion (A) is factually correct.

• Evaluating Reason (R): The list contains famous examples of malware and network threats:

• ILOVEYOU and MyDoom are famous self-replicating worms.

• CryptoLocker is a notorious ransomware program.

• Slammer (SQL Slammer) is a fast-spreading computer worm.

• Although technically classified under specific categories like ransomware or worms, in general computer literacy terms, they are commonly discussed as viruses or malicious codes. Thus, Reason (R) is factually correct.

• Causal Connection: The Reason lists specific examples of malicious software. However, listing examples of viruses does not explain the functional definition or mechanism of what a virus is (Assertion). Listing examples describes which programs exist, not why a virus is defined as code designed to hamper resources.

• Thus, both (A) and (R) are correct, but (R) is not the correct explanation of (A). This corresponds to Option (B).

Step 3: Final Answer:
The correct option is (B).
