determine whether the argument is valid or invalid. If it is invalid, select a counterexample.
-1. ∼(E $\lor$ F)
2) ∼F ⊃ (G ⊃ H)
3) G ≡ ∼H / ∼G

A) Valid
B) Invalid. Counterexample when E, F, and G are true and H is false
C) Invalid. Counterexample when E and G are true and F and H are false
D) Invalid. Counterexample when F and G are true and E and H are false
E) Invalid. Counterexample when G is true and E, F, and H are false
