Concept: The valid conclusion follows from the contrapositive of the given implication $m \Rightarrow n$.Explanation:The given statement is $m$: Edna is respectful and $n$: Edna is brilliant.We are given the implication $m \Rightarrow n$.The contrapositive of $m \Rightarrow n$ is $\neg n \Rightarrow \neg m$.That means: If Edna is not brilliant, then Edna is not respectful.This is exactly option A: $\neg n \Rightarrow \neg m$.The other options are not valid converses, inverses, or logical consequences of $m \Rightarrow n$.Answer: A. $\neg n \Rightarrow \neg m$.
