D Correct answer
Explanation

The 'uname -a' command displays comprehensive system information including the kernel name, network node hostname, kernel release, kernel version, machine hardware architecture, and operating system. Commands like 'pwd' (print working directory), 'uptime' (system uptime), and 'top' (running processes) serve different purposes and don't provide OS-level information.
