Final answer:
For the given domain, the only logical equivalent to ∀xP(x) is (P(a) ∧ P(b) ∧ P(c)), where P is true for each domain element a, b, and c.
Step-by-step explanation:
The question seems to be asking to identify the logical equivalents given a domain of x which includes a, b, and c. In propositional logic, the statement ∀xP(x), which reads as "for all x, P(x) holds", is true if P(x) is true for every element in the domain of x. Thus, among the choices given, option a. (P(a) ∧ P(b) ∧ P(c)) is logically equivalent to ∀xP(x) because it asserts that P(x) holds for all instances of x in the given domain. The rest of the choices represent different logical constructs that do not match the universal quantifier ∀ applied to P(x).
