Answer:

The answer is "Option a and Option f"

Explanation:

In the given question option a and option f is correct because both commands use the "cp" command, which is used to copy files and in this command, in option a, it uses the file "from cs250 to cs150", and an option "f" uses the "cs250 with '.h' that is a file extension", and the wrong choice can be defined as follows:

  • In choice b, it is wrong because it is not a correct command.
  • In choice c, in this command we use "?" symbol, that is wrong.  
  • In choice d and e both were invalid.
