The question said two line that are not in the same plane that no not intersect and are not parallel.
We should determine what the lines are called.
Let's consider the characteristics of a skew:
(1) two limes are not in same plane.
(2) two lines are not parallel.
Therefore the above statment in the question is a Skew.
Thus,
Therefore, the correct option is A, which is Skew.
