If a person must select K before selecting M in Formal Logic, how would you write this relationship?

K → M, ~M → ~K
K → ~M, ~K → M
M → K, ~K → ~M
M → ~K, ~M → K

The correct answer is: K → M, ~M → ~K

In Formal Logic, the relationship "If a person must select K before selecting M" can be correctly represented as "K → M," which means K must be selected before M can be selected. Additionally, the relationship "If M is not selected, then K is not selected" is represented as "~M → ~K," indicating that if M is not chosen, then K cannot be chosen either. This relationship is accurately captured in choice A. Choices B, C, and D do not represent the given relationship correctly. They either reverse the order of selection or do not reflect the condition where M must be selected after K. Therefore, they are not the correct representations of the relationship described in the question.
