Wrong trigger. If we want to prove that Keisha’s act was justified, we want to use principle (2). We want to know that her conscience rqeuired the act. But (A) doesn’t establish that her conscience required the act. (And no, the contrapositive of (1) doesn’t support this argument. The contrapositive of (1) tells us that IF an act is justified, then .... That doesn’t allow us to conclude that an act is justified.

Wrong trigger. To prove that an act is NOT justified, we want to use principle (1). We want to establish that the act was done out of self interest alone. But (B) doesn’t establish that. (And no, the contrapositive of (2) doesn’t allow us to conclude that an act wasn’t justified. The contrapositive of (2) means IF an act was not justified, then .... That doesn’t allow us to prove that an act is not justified. If you think it does, you’re confusing sufficient and necessary conditions.)

Wrong trigger. If we want to prove that Georgette’s act was justified, we want to use principle (2). We want to know that her conscience rqeuired the act.

(D) establishes that Maria violated the law because her conscience required it. Thus, according to principle (2), we can conclude that her act was justified.
