Critical Reasoning (CR) | Since empathy is essential for people to be willing to follow moral co

Hi,
I am writing up my understanding, please correct me if I am missing something

Say
people to be willing to follow moral codes -> X
empathy -> Y
civilized society -> Z
Stimulus:
Since Y is essential for X, Z cannot be without Y.
My take
Z has X i.e Z cannot be without X.
Option C says
If X then it is Z which is not necessary.
So OA is A
