Which of the following is not a major group of flower types?

The correct answer is "C. Bright," because it does not represent a recognized major group of flower types in the floral design industry. In floral classification, flowers are typically categorized into distinct groups based on their structural characteristics and roles in arrangements.

Mass flowers are usually large and rounded, providing a focal point or fullness to arrangements. Form flowers are unique in shape and are used to create visual interest and define the structure of a floral design. Filler flowers, on the other hand, are smaller and are used to fill empty spaces within an arrangement, enhancing fullness without overshadowing the main flowers.

"Bright" is not a technical term used to classify types of flowers in this context. It might refer to a color characteristic but lacks the specificity that defines the traditional groupings of mass, form, and filler flowers. Understanding these groupings is essential for creating balanced and visually appealing floral arrangements, as each type plays a distinct role in the overall design.
