Tutor  Fombitz just noticed that the answers list does not match to the question.



I want to confirm it for new generations of students,  who may read this post in the future: 


the problem is posed  INCORRECTLY,  the answers list is not consistent with the question.



I address my note to the future generation of students,  but not to the persons who created/submitted this post,


because,  in my view,  it is useless to explain anything to those who compose such gibberish: 
they either do not understand what they post,  or do not read it,  at all.



                                        Or  BOTH.
