Final Answer :
C
Explanation :
Program scope tags can only be accessed by routines within a specific program. This means that other programs or routines outside of the specific program will not be able to access or use these tags. Base tags and alias tags are not limited to a specific program and can be accessed by other programs or routines. Controller scope tags are limited to a specific controller, but can still be accessed by other programs or routines within that controller.
