Selected Answer: C
Enabling the NX bit ensures that the rewritten application can effectively use the mprotect() system call to manage memory execution permissions, thereby strengthening its defenses against exploitation tools that attempt to execute code from unauthorized memory regions. This approach aligns with best practices in modern application security to mitigate memory-based vulnerabilities
