Show answer & explanation
Correct answer: B
CONCEPT
In a multiple-statement ICT item, each statement must be tested against the actual function of the technology, and absolute words such as “always” must be checked. Encryption transforms plaintext into ciphertext to protect data confidentiality; anti-malware tools remove viruses, while authentication and authorization govern entry to a computer system. Microblogging is built for brief, rapidly posted updates on standardized platform layouts, while a LAN is defined by local geographic scope and can use wired or wireless media.
APPLICATION
Statement A combines encryption with virus destruction and system-access prevention. Encryption protects data confidentiality; anti-malware tools disinfect a system, and authentication and authorization enforce system access. Because the statement conflates these separate controls, the complete statement does not hold.
Statement B describes the design of microblogging. The format prioritizes brief, rapidly posted updates on standardized platform templates; those design choices impose short-post limits and comparatively limited layout customization. The statement holds in the intended ICT sense.
Statement C uses the absolute word “always.” A LAN may use wired Ethernet or wireless Wi-Fi, so wireless transmission is not compulsory.
CROSS-CHECK / CONTRAST
A only depends on the compound encryption claim, including its malware-removal part.
B only selects the microblogging-constraints statement.
B and C only also depends on the universal wireless-LAN claim.
A and C only depends on both the malware-removal and universal-wireless claims.
RESULT
Only statement B is true. Therefore, the answer is “B only.”
