Let v(x) mean x is a vegetarian, m(y) for y
is meat, and e(x, y) for x eats y. Based on these, consider the following
sentences:

I. ∀x
v(x) ⇔ (∀y e(x, y) ⇒ ¬m(y))

II. ∀x
v(x ) ⇔ (¬(∃y m(y) ˄ e(x, y)))

III. ∀x (∃y
m(y) ˄ e(x, y)) ⇔
¬v(x)

One can determine that

(A) Only I and II are equivalent sentences

(B) Only II and III are equivalent sentences.

(C) Only I and III are equivalent sentence.

(D) I, II, and III are equivalent sentences.

Answer: D
