The setting for the visibility of custom tabs is default off for all users when they are deployed via change sets without including the profile settings or permission sets. This means that the custom tabs are not visible in any apps or navigation menus for any users unless they are manually added by each user or by an administrator3. Option B, C, and D are not correct settings for the visibility of custom tabs.
