Correct Answer:
A-2, B-1, C-4, D-3
Explanation
Each system call is categorized based on its function within the operating system:
A. fork() → 2 (Process Control): Used to create a new child process that is a duplicate of the calling process.
B. chmod() → 1 (File Management): Used to change the permissions (read, write, execute) of a specified file or directory.
C. ioctl() → 4 (Device Management): Used for device-specific input/output operations and device configuration controls.
D. sleep() → 3 (Information Maintenance): Suspends process execution for a specified interval, involving time management and process timer maintenance.
Therefore, the correct mapping is A-2, B-1, C-4, D-3.
