Kite and Rectangle

Trapezoid and Kite

Square and Rhombus

Rhombus and Trapezoid

Answer: third option. square and rhoumbus.

Justification:

The only set of two parallelograms is the third one: square and rhombus.

Square, rhombus and rectangle are parallelograms.

Some kites may be parallelograms but not all the kites are parallelograms and trapezoid are not parallelograms.
