Correct answer: B
In the Windows API, the WriteConsole() function is used to write characters directly to the console screen. The parameter hConsoleOutput must be a valid console output handle, which is commonly obtained using:
GetStdHandle(STD_OUTPUT_HANDLE)
This handle represents the standard output device (console screen).
