ques number 17 remained unanswered I think.

F(x) has slope 1 when x  ∈ [0,1]
since it is closed interval we can conveniently say that F(x) =  0, x<0
                                                                                    x , 0 <= x <= 1
                                                                                    1 , x>1
differenting F(x) to get f(x)
f(x) = 1 , 0 <= x <= 1
      = 0, elsewhere

hence option b
