Point symmetry: symmetry around a point
If you were to place a point in the center of the shape, and place a "pin" there, then rotate the shape around that point 180 degrees, the shape would match up. This shape has point symmetry.
Line symmetry: symmetry across the point
If you were to draw a line through the top right and bottom left corner of the shape, and fold the shape over the line, it would match up. This shape has line symmetry.
So, c. This has both point and line symmetry.
