Explanation:

- A square is a type of rectangle. A square has all sides equal and all angles at 90 degrees, whereas a rectangle also has all right angles but only opposite sides equal.

- A rhombus is a type of parallelogram. A rhombus has all sides equal, while a parallelogram has opposite sides equal.

- Cuboid refers to a three-dimensional shape related to a rectangle, not a rhombus or parallelogram.

- Trapezium is a quadrilateral with only one pair of parallel sides, not directly related to a rhombus.

- Kite is a quadrilateral with two distinct pairs of adjacent sides equal, different from how a rhombus or parallelogram is defined.

- Parallelogram is the correct relation to a rhombus, as a rhombus is a special kind of parallelogram.

Hence, the correct answer is Parallelogram.
