Dear all,
I believe the answer list should be reviewed:

You had to select 2 options

• The given line of code will throw an exception at run time.

• f.mkdir(); will create directory d under c and directory e under d.

• f.mkdirs(); will create directory d under c and directory e under d.

• f.getParentFile() will return a File Object representing c:\a\b\c\d

• None of these.

From a pure logical perspective: How can you choose the last one and at the same time having to chose 2 options? If I select "None of these" it means "all the others are false". So you cannot choose 2 options if you select that one: It makes no sense.
Meaning that even if someone doesn't know the answer at all, he/she can definitely exclude the last option. I think the "None of these" option works well where there is only one possible response.
In this case the last one should be either removed or replaced with another false option.

What you are saying is logically correct. However, some users hide the number of correct options that you have to select for each question, just to make the questions harder to answer. In that case, the option is fine.
We will improve it as per your suggestion.

thank you for your feedback!
