It is difficult to determine which Venn diagram is not correct without being able to see the diagrams. Please provide additional information or a visual representation of the Venn diagrams.
Based on the given options, the Venn diagram that is not correct is the one that includes "Rectangles" as a separate category. Rectangles are a type of quadrilateral that can be both squares and rhombuses, so they should not be represented as a separate circle outside of the squares and rhombuses circles.
