HOW DO YOU DETERMINE THE CORRECT ANSWER?

Hi, this game mostly depends on M, since we know a lot if m is in t or in g. For this question, we are given the condition that s and p can't be together, so let's see if either of our M scenarios have s and p together. It looks like if m plays golf then they are, so m can't play golf, so m plays tennis. So, we have G: L P T: O S M We have not yet placed K yet. However, we know that m and p cannot play the same sport, so C cannot happen, making it correct.
