Final answer:
To create executable code and run a program, a source code file needs to be recompiled if modified, the user needs access to the object code file, and the user must have access to the source code file containing the implementation details.
Step-by-step explanation:
In order to create executable code and run a program, there are certain requirements. One of the statements that is true is that if a source code file is modified, it needs to be recompiled. This is because when the source code is modified, the changes need to be compiled into object code before it can be executed.
Another statement that is true is that the user must have access to the object code file. The object code file is the compiled version of the source code, and it is what the computer actually executes. So, the user needs to have access to this file in order to run the program.
Lastly, the user must also have access to the source code file containing the implementation details. This is because the source code file contains the instructions and logic of the program, and without it, the user would not be able to modify or understand the program.
