Answer 1

The command cat >x in unix c) creates a file x and waits for the user to give input from the keyboard.

cat command (concatenate) allows us to create single or multiple files, view the contents of files, concatenate files, and redirect output in terminal or in files.

If we give cat >x command then a file named x is created and allows the user to type input from the keyboard. After giving the input , user has to press Ctrl, then type D to exit.

Then the user can see the data of file x by typing cat x command.
