UGC NET Questions (Paper – 1)

Statement D is the only wrong statement because Internet connectivity actually increases exposure to malware instead of ensuring immunity. Statements A, B and C correctly define malware, emphasise the value of antivirus software and warn about risky attachments. No technology can make a system permanently immune to all attacks; continuous vigilance and updates are needed. Therefore the option that selects only D as wrong is the correct answer.

Option A:
Option A is incorrect because it groups A and D as wrong statements. Statement A is accurate in using malware as an umbrella term for various malicious software types. Including this correct statement among the wrong ones makes the option logically inconsistent.

Option B:
Option B is correct because it isolates D as the sole incorrect statement while accepting that A, B and C are valid security guidelines. It underlines that connecting to the Internet does not eliminate risk and that protective measures remain vital.

Option C:
Option C is incorrect because it labels C and D as wrong. C is true, as attachments from unknown senders frequently carry malware or phishing attempts. Combining one true statement with a false one produces an invalid set.

Option D:
Option D is incorrect because it treats B and D as wrong statements. Statement B is a sound recommendation about antivirus use, so grouping it with the false claim in D misrepresents good security practice.

Statements A, B, D and E describe the basic structure and usage of email. An address combines a local part and domain, CC sends copies, attachments carry files and spam denotes unsolicited messages. Statement C is false because BCC hides addresses from other recipients, and F is false because clear subject lines are recommended in professional contexts. Hence A, B, D and E only are correct.

Option A:
Option A is incomplete because it omits E and therefore does not capture the concept of spam, which is central to understanding email communication. A, B and D are true but do not exhaust all correct statements.

Option B:
Option B is correct because it includes every accurate statement about addressing, fields, attachments and spam while leaving out misconceptions about BCC and subject lines. It aligns with standard email practices.

Option C:
Option C is incorrect because it adds F, claiming that subject lines should be avoided; this contradicts norms of clarity. It also includes C, which misrepresents BCC behaviour, so the combination is invalid.

Option D:
Option D is incorrect because it leaves out B and does not mention the CC field. Although A, D and E are true, ignoring CC means not all correct statements are included.
