UGC NET Questions (Paper – 1)

Statements A, B and C correctly describe different software licence models, whereas statement D is misleading. Proprietary software generally hides source code and is used under licence restrictions. Open-source licences explicitly allow code access and modification, and freeware is cost-free to use but not necessarily open source. Shareware is typically a trial or limited-use model that may require payment after a period, so it cannot be treated as permanently free and unrestricted. Hence, the combination A, B and C only is correct.

Option A:
Option A is correct because it includes all three accurate statements about proprietary, open-source and freeware models while excluding the inaccurate description of shareware. It recognises that cost-free use and code openness are distinct dimensions covered by different licence types. By omitting D, this option avoids confusing trial software with permanently free software.

Option B:
Option B is incorrect because it lists only A and B as correct and omits C. Although A and B are true, C is also correct in clarifying that freeware refers to price, not necessarily openness of source code. Leaving out C makes the description of software licences incomplete.

Option C:
Option C is incorrect because it groups B, C and D and treats D as correct. While B and C are true, D wrongly claims that shareware never requires payment and is always unrestricted. Including a false statement and excluding A means this combination cannot be accepted.

Option D:
Option D is incorrect because it combines A and C with D and therefore accepts the mistaken idea that shareware is always free and fully unrestricted. Although A and C are true, the presence of D makes the overall combination wrong.

Statements A, B, C and E clarify major software licensing categories. Open-source offers access to source code, freeware is free to use but usually closed source, shareware involves trial with potential payment and “free” in free software is about freedoms rather than price. Statement D is false because proprietary licences typically restrict modification and redistribution, and F is false because no software model guarantees perfect security. Therefore A, B, C and E only are correct.

Option A:
Option A is correct because it includes all true statements while excluding misleading views about proprietary rights and absolute security. It accurately differentiates licensing models in a way that is relevant for ICT users in education.

Option B:
Option B is incomplete because it omits E and hence does not differentiate between “free” as in price and “free” as in freedom. Although A, B and C are correct, they do not fully explain the philosophy of free software.

Option C:
Option C is incorrect because it includes F, which overstates the security of open-source software. Even well-audited code can have bugs, so adding F makes the whole combination wrong.

Option D:
Option D is incorrect because it leaves out A and includes only B, C and E. Excluding A omits the central definition of open-source, and the set fails to contain all correct statements.
