UGC NET Questions (Paper – 1)

Statements A through E accurately capture how basic quantifier notions are understood and used in reasoning and exams. “At most one” and “exactly one” require structured combinations of quantifiers and identity conditions, as noted in C and D. E is true because Paper 1 often expects conceptual understanding without full symbolism. F is false since the existential quantifier alone cannot express “at most one” or “exactly one” without additional logical resources. Therefore A, B, C, D and E only is the correct combination.

Option A:
Option A is incomplete because it omits E, not acknowledging the UGC NET context in which such quantifier reasoning appears. While A, B, C and D are true, they do not fully answer the question as posed.

Option B:
Option B is correct since it gathers all the true statements about quantifiers and their informal use in exam questions, and it excludes F, which overstates the expressive power of a single quantifier. This matches how quantifier ideas are treated at the Paper 1 level.

Option C:
Option C is wrong as it includes F, suggesting that existential quantification alone can handle “at most one” and “exactly one”. Without identity and sometimes universal conditions, these claims cannot be captured properly. Thus this option is incorrect.

Option D:
Option D is also incorrect because it omits B, losing the basic reading of the universal quantifier, and still fails to include all the correct statements. As such, it cannot be the right choice.
