C.
Access control list (ACL)

D.
Discretionary access control entry (DACE)

Explanation:

Access Control Entry (ACE) is an entry in an object’s discretionary access control list (DACL) that grants permissions to a user or group. It is also an entry in an object’s system access control list (SACL) that specifies the security events to be audited for a user or group.
Answer option C is incorrect. Access Control List (ACL) is a rule list containing access control entries that are used to allow or deny access to network resources.
Answer option D is incorrect. There is no such access control entry as DACE. Answer option B is incorrect. Security Identifier (SID) is a unique number that identifies a user, group, and computer account. When a user, group, or computer account is created, a unique SID is issued.
