UGC NET Questions (Paper – 1)

Statements A, B and C correctly state the truth conditions for conjunction, inclusive disjunction and negation, while E notes their usefulness in exam problem solving. D is false because a statement and its negation cannot be simultaneously true on the same assignment. F is false since two independent propositional variables require 2² = 4 rows, not three. Thus the true statements are A, B, C and E only.

Option A:
Option A is incomplete as it omits E, not mentioning the exam advantage of knowing these tables. While A, B and C are true, they do not fully answer the question, which includes UGC NET context.

Option B:
Option B is wrong because it includes F, which miscalculates the number of rows in a truth table for two variables. Accepting F makes the overall combination incorrect.

Option C:
Option C is correct as it combines the accurate truth-conditions with their practical relevance for Paper 1, and it rejects D and F, which contradict basic logical facts. This aligns with standard teaching for UGC NET.

Option D:
Option D is incorrect because it includes F and omits A, losing the fundamental point about conjunction while adding a false statement about truth table size. Therefore it cannot be chosen as correct.
