First, let's look at the properties of the geometric terms you were given.
Quadrilateral - a four-sided figure
Rectangle - four sides, two pairs of opposite sides are parallel, four right angles
Rhombus - four sides, two pairs of opposite sides are parallel, all sides equal
So we're looking for a shape that has four sides that are all equal, has two pairs of parallel sides, and has four right angles. The shape that fits what Ye Li drew is a square. Squares have two pairs of parallel sides (like a rhombus and rectangle), four right angles (like rectangles), and four sides that are equal (like a rhombus). A square is both a rectangle and a rhombus.
