Concept:The negation of an implication $p \Rightarrow q$ is the statement that makes the implication false.Explanation:Recall the truth table for $p \Rightarrow q$.$p \Rightarrow q$ is false only when $p$ is true and $q$ is false.In all other cases, the implication is true.Therefore, its negation must express the exact condition under which the implication fails.That condition is: $p$ is true and $q$ is false.In logical notation, this is written as $p \land (\sim q)$.Answer:Option C: $p \land (\sim q)$.
