  2. exit 0
  3. #begin script
  4. #!/bin/bash
Explanation
Answer - D - #!/bin/bash should be included at the beginning of every shell script.

Key Takeaway: The #!/bin/bash indicates that the script should be run in the bash shell by overriding any shell the user has chosen. This is very helpful since it alerts the user to type appropriate scripts for the bash shell.
