Given below are two statements:
Statement I: Denial-of-Service (DoS) attack is the large number of requests sent at the same time to the web server, thereby causing the server to crash.
Statement II: Virus is a self-replicating malicious software causing computer to run slowly.
In light of the above statements, choose the most appropriate answer from the options given below.
Answer: A. Both Statement I and Statement II are true — CONCEPTA denial-of-service attack targets availability: it exhausts finite server or network resources so legitimate users cannot obtain service. A computer…

Correct answer: A
CONCEPT
A denial-of-service attack targets availability: it exhausts finite server or network resources so legitimate users cannot obtain service.
A computer virus is malicious code that replicates by attaching to host code; its activity can consume resources and degrade performance.
APPLICATION
Statement I describes a common flood-based DoS mechanism. A burst of requests can exhaust connection, processor, memory, or bandwidth capacity, leaving a web server unresponsive or causing it to crash.
Statement II describes two established virus characteristics: copying itself through infected host code and causing performance degradation when malicious activity consumes system resources.
CONTRAST AND CROSS-CHECK
Both statements true: this matches the standard textbook reading of the two descriptions.
Both statements false: this rejects both the request-flood mechanism and virus replication/resource effects.
Statement I true and Statement II false: this overlooks that viruses copy themselves through host code and may slow a system.
Statement I false and Statement II true: this overlooks request flooding as a standard DoS mechanism.
The wording states common mechanisms and possible effects, not that every DoS attack must crash a server or every virus must visibly slow a computer.
Therefore, both Statement I and Statement II are true under the intended textbook interpretation.
