Library section
-
Environment definition
-
Activity definition
-
NONE OF THE ABOVE
C
Correct answer
Explanation
The correct answer is C (Activity definition). In an Easytrieve program, the Activity definition section is the only mandatory section. It contains the program logic and processing statements. The Library section and Environment definition are optional - Library is for defining reusable code, and Environment definition is for file and variable declarations. A minimal Easytrieve program can consist solely of activity definitions.
