Solution

The correct options are
A A line of symmetry divides a graph into two mirror-image halves.
D Line of symmetry will always be a vertical line in all parabolas whose general formula will be $x = c$ .
Line of symmetry of parabola exists exactly at vertex of parabola

It divides parabola into exactly two equal parts and those parts are mirror images of each other

Line of symmetry is always vertical whose general form is $x = c$
