the equation of a line parallel to the y-axis is x = c.
therefore statement C is false.
statement C is the equation of a line parallel to the x-axis, not the y-axis.

statements A and B are both true.

.
(A)  Vertical straight line (parallel to y-axis) is not (does not represent) a function, at all.

     Therefore, statement A is FALSE.



(B)  The statement B is TRUE.



(C)  The equation of a line parallel to y-axis is x= c.

     Therefore, statement (C) is FALSE.



So, the answer to the problem is  " 2. Only B. ".
