Which of the following commands will print the exit value of the previous command to the screen in bash?

The special shell variable `$?` contains the exit status of the last executed foreground command, which `echo` will print to standard output.

`$#` contains the number of positional parameters passed to a script or function, not the exit status.

`$exit` is not a standard shell variable for the exit status; `exit` is a command.

`$status` is used in some shells like csh/tcsh for the exit status, but not in bash.

`$&}}` is not a valid or recognized shell variable or construct.
