Statements: J < M > K < N ≤ L. Conclusions: I. L ≥ M II. J = K. Which of the conclusions is definitely true?

Correct answer C. Neither conclusion I nor II is true

Explanation

I: in M > K < N ≤ L the signs change direction, so L and M are not related and I fails. II: in J K the signs change direction, so J and K are not related and II fails.
