UGC NET Questions (Paper – 1)

Statements A, B, C and E correctly describe how propositions are understood in logic and how they are used in reasoning questions, while D and F are false. A is right that propositions are truth-apt contents of declarative sentences, and B is right that questions and commands are normally excluded. C is correct that different sentences can express the same proposition, and E rightly notes that identifying propositions helps in argument analysis. D is wrong because some grammatical sentences lack a clear truth value, and F is wrong because long or complex sentences can also express propositions.

Option A:
Option A is correct because it includes exactly A, B, C and E, which are the four true statements in the list. It avoids D, which overgeneralisers grammaticality, and F, which incorrectly restricts propositions to short sentences. This combination matches the logical treatment of propositions and their role in UGC NET reasoning.

Option B:
Option B is incorrect because it omits statement E, which truly points out the exam relevance of identifying propositions. Although A, B and C are all true, leaving out E means this option does not contain all the correct statements. Hence it gives only a partial picture of the role of propositions.

Option C:
Option C is wrong because it includes F, which falsely claims that only short simple sentences can express propositions, and it also omits A, the basic definition. Without A, the notion of a proposition as a truth-apt content is lost. Including a false statement and excluding a central true one makes this combination unacceptable.

Option D:
Option D is incorrect because it includes F and leaves out B. By accepting F, it endorses an unjustified restriction on propositions, and by omitting B it ignores the standard exclusion of questions and commands. This mixture of omission and error prevents the option from representing the full set of correct statements.
