GMAT Critical Reasoning (CR) | Re: Kale has more nutritional value than spinach. But since

Subject question can be solved mathematically by making inequalities and finally it would lead to A.
Input: K>S, C>L ===> K>L?

A. C>K, tha gives us no solid evidence to assume that in fact K>L. That's possible answer.
B. S>L, direcltly leads to K>L
C. S>C, directly leads to K>L
D. S=C, leads to K>C and directly denotes that K>L

Thus, A is the only possible option for this "EXCEPT" question, as long as other options obviously strengthens the claim.
