From the given premises, we can conclude that there are some X which are not Y and all X are Z. Therefore, it can be logically inferred that some Z are not Y. Option A correctly represents this conclusion. Option B and D are incorrect because there is no evidence to suggest that all X are not Y, or that no Y is X. Option C is also incorrect, as it is possible for all Z to be X or for some Z to be X, given the premises provided.
