Question

¿qué es?
rombo azul
cuadrada azul
óvalo azul
azul cuadrada

Explanation:

The image shows the Windows logo, which consists of blue square - like (quadrilateral with four right angles, so square - related) shapes. The option "cuadrada azul" (blue square - shaped) best describes the logo's appearance. "rombo azul" (blue rhombus) is incorrect as the logo's shapes are more square - like than a general rhombus. "óvalo azul" (blue oval) is wrong as the shapes are not oval. "azul cuadrada" has an incorrect word order for describing the shape and color in Spanish (the correct order for a noun - adjective description of a shape - color is shape first then color in this context).

Answer:

cuadrada azul
