Correct option is B
From (1) M > Q and (3) N ≤ M,
we can only say: Q < M and N ≤ M.
There is no direct relation between Q and N —
N could be equal to M or less than M, while Q is less than M.
So, Q could be less than, equal to, or greater than N depending on exact values.
Conclusion I is not definitely true.
From (1) M > Q and (2) P ≥ M,
we can combine: P ≥ M > Q => P > Q (definitely).
