    A,C are correct. See https://docs.vmware.com/en/VMware-vSphere/5.5/com.vmware.vsphere.resmgmt.doc/GUID-69C738B6-5FC8-4189-9CB5-DD90A5A05979.html

    If two VM-VM affinity rules are in conflict, you cannot enable both. For example, if one rule keeps two
    virtual machines together and another rule keeps the same two virtual machines apart, you cannot enable
    both rules. Select one of the rules to apply and disable or remove the conflicting rule.

    When two VM-VM affinity rules conflict, the older one takes precedence and the newer rule is disabled.
    DRS only tries to satisfy enabled rules and disabled rules are ignored. DRS gives higher precedence to
    preventing violations of anti-affinity rules than violations of affinity rules.
