Show answer & explanation
Correct answer: A
Answer: Create – process → Fork; WaitForSingleObject → Wait; CreateFile → Open; CloseHandle → Close.
Create – process (Windows) corresponds to Fork (UNIX).
Reason: Windows CreateProcess (or Create for a process) spawns a new process; UNIX fork creates a new process by duplicating the calling process.
WaitForSingleObject (Windows) corresponds to Wait (UNIX).
Reason: Both calls block until a specified process or child process finishes or a particular object/state is signaled.
CreateFile (Windows) corresponds to Open (UNIX).
Reason: Both obtain a handle or file descriptor to access a file for reading/writing.
CloseHandle (Windows) corresponds to Close (UNIX).
Reason: Both release the handle or file descriptor and free associated resources.
