The syntax for creating a remark in an access list is correctly represented by the option that starts with "(config)#remark ACL DESCRIPTION." Remarks in access lists are used to provide annotations or comments about the purpose or intent of the rules defined in the access list. This can be particularly helpful for documentation and clarity, especially in larger or more complex configurations.

To properly format a remark, the "remark" command is used in configuration mode followed by the comment text. This helps network administrators to keep track of changes or the purpose of specific access controls without affecting the operation of the access list itself.

The other options present variations or commands that do not correctly incorporate the syntax used in Cisco IOS for adding remarks to access lists, thereby making them invalid choices for this specific action. This highlights the importance of using the exact syntax as it pertains to the functionality provided by Cisco devices.
