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.
