B) the code doesn't change during execution.
C) the code changes are identical for each process.
D) All of the above.

Quizplus · Accepted Answer

Paging allows the code to be stored in a separate read-only section of memory that is shared among all processes. This ensures that the code remains unchanged during execution, making it easier to share without concerns of conflicting modifications. Option A is incorrect as reentrant code is designed to be executed by multiple processes concurrently without interfering with each other's execution. Option C is also incorrect as each process may have different execution paths that require modifications to the reentrant code.
