A quadrilateral has 4 sides. It has no vertices as a quadrilateral is a two dimensional shape. * * * * * A vertex is a point where two or more lines (edges) meet. There is no requirement for the figure to be three dimensional. So the correct answer is that is has 4 vertices.
A quadrilateral cannot have only three vertices.
