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

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