Which of the following items constitutes wedding flowers?

The answer focuses on the comprehensive nature of wedding flowers, encompassing various floral elements that contribute to the overall ambiance of the event. Wedding flowers typically include not only the bridal bouquet but also a range of additional floral arrangements such as corsages for important family members and table decorations or centerpieces that enhance the reception setting.

In a wedding context, each type of floral piece plays a significant role in aesthetics and symbolism. The bridal bouquet is a focal point, while corsages add to the formal attire of close family members, and table decorations bring a cohesive design theme to the event, often reflecting the couple's style and color choices.

Considering this, the other options fall short by restricting the definition of wedding flowers. For instance, limiting it to just the bride's bouquet, guest centerpieces, or only the flowers used during the ceremony does not encompass the full scope of floral design elements involved in weddings. This broader understanding of what constitutes wedding flowers helps ensure that all important aspects are considered in the planning and design process.
